Sum of Consecutive Integers When Gauss ( biography ) was ten years old, his teacher gave his class an assignment that was sure to keep the kids busy for quite a while. The students were told to add up the numbers from 1 to 100. How to solve integer word problems that involve the sum of consecutive integers? Examples: 1. The sum of two consecutive integers is 99. Find the value of the smaller integer. 2. The sum of two consecutive odd integers is 40. What are the integers? 3. The sum of three consecutive even integers is 30. Find the integers. Show Step-by-step Solutions

Jun 24, 2019 · To represent consecutive numbers algebraically, let one of the numbers be x. Then the next consecutive numbers would be x + 1, x + 2, and x + 3. If the question calls for consecutive even numbers, you would have to ensure that the first number you choose is even. In any event, this sum must be even, so 3 consecutive even integers would be n, n+2 & n+4 whose sum is 3n + 6. Set that to either 78 or 7878, whichever is intended, & solve for n. If 78 is their grand total, then those 3 consecutive even numbers have to be 24, 26 & 28.

asked • 12/13/17 Find three consecutive even numbers if it is known that the sum of the squares of the first 2 is equal to the square of the third number. There are two answers for this question.

= Sum(A1:C1) + D9 + E12 + G25. You can even use another SUM function: = Sum(A1:C1) + SUM(G1:H1) But you are just telling Excel which cells in your spreadsheet that you want to include in your addition formula. The second method to add up non-consecutive cells starts in the same way: use a SUM function, and separate your consecutive cells with a ... 2. To sum the 4 largest numbers (don't be overwhelmed), add the SUM function and replace 2 with {1,2,3,4}. 3. Finish by pressing CTRL + SHIFT + ENTER. Note: The formula bar indicates that this is an array formula by enclosing it in curly braces {}. Do not type these yourself. They will disappear when you edit the formula.

Mar 10, 2008 · So adding the 3 even integers to get 150: n + n + 2 + n + 4 = 150. 3n + 6 = 150. 3n = 144. n = 48, so n + 2 = 50, n + 4 = 52. The three even integers that add up to 150 are: 48,50,52. For odd... Introduction A positive integer n cubed always can be represented as the sum of consecutive odd numbers. Yet finding this decomposition can seem difficult, as is apparent from considering examples , e.g. , "find 'cubes as odds' representations for 125 = 5 3 , 343 = 7 3 , or 117,649 = 343 3 ." Let x = the smallest even integer, x + 2 = the next even integer, and x + 4 = the largest even integer. Write the equation x + x + 2 + x + 4 = –78. Simplify the equation as 3x + 6 = –78. Solve the equation by subtracting 6 and dividing by 3 on both sides of the equation. Check that the sum of the integers –28, –26, and –24 is –78.

Mar 27, 2008 · the sum of three consecutive odd intergers is 27 for exsample the sum of three consecutive intergers is 42 x+(x+1)+(x+2) Tutor: mit2008 , Graduate Student replied 11 years ago Let x be the first integer, so x+2 and x+4 are the second and the third one, respectively. Consecutive Even Integers: n, n + 2, n + 4 for odd integer n Sum of Second and Third Integers: (n + 2) + (n + 4) = 2 n + 6 Since sum of the second and third integers equals four times the first integer, it follows that: 2 n + 6 = 4 n 4 n − 2 n = 6 2 n = 6 n = 3 ∴ Three consecutive odd integers are 3, 5 and 7

The first block is a unit block and the dashed line represents the infinite sum of the sequence, a number that it will forever approach but never touch: 2, 3/2, and 4/3 respectively. Examples of a geometric sequence are powers r k of a fixed number r , such as 2 k and 3 k . On the other hand ,If there are even number of digits in set of consecutive numbers like set of four consecutive numbers (4,5,6,7) or 6 digits are there, say (3,4,5,6,7,8), then in this case the sum of all integers is never divisible by the number of digits present in the set . For example 2+3+4+5 = 14 is not divisible by number of digits i.e. 4 Applications: Number problems and consecutive integers. Sum of 3 consecutive odd integers is -3, what are the integers? Solution A number is odd if it has the following format: 2n + 1 Let 2n + 1 be the first odd integer Let 2n + 3 be the second odd integer Let 2n + 5 be the third odd integer Since the sum is equal to -3, we get the following ...

But 13 cannot be expressed as the sum of distinct generalized Fibonacci numbers, we would have to repeat one 13 = 7 + 3 + 3, or another 13 = 7 + 3 + 1 + 1 + 1. Similarly for 14, 15 and 16. It gets worse, since the largest number we can express even with all 5 of the first 5 terms of the generalized Fibonacci sequence is 1 + 1 + 3 + 7 + 17 = 22.
