Question

In a list of 7 consecutive integers, the sum of the first and last is 518. find the largest.

Answer 1

262

Explanation:

If x is the first integer, then x+1 is the second, x+2 is the third, and so on. Meaning the 7th term in the list is x+6.

x + x + 6 = 518

2x = 512

x = 256

The first integer is 256, so the last integer is 262.
