Question

The sum of 5 consecutive even numbers is 310. What is the third number in this sequence?

Answer 1

58, 60, 62, 64 and 66

Explanation:

Let the first number be n. Then the five consecutive even numbers are

n, n+2, n+4, n+6, n+8. Adding these together and setting the sum equal to 310, we get 5n + 20 = 310. Thus, 5n = 290, and n = 58.

The five consecutive numbers are 58, 60, 62, 64 and 66.

Answer 2

58,60,62,64,66 equals 310 so the third number is 62
