Question

If the sum of three consecutive numbers is 210, what is the largest of the three numbers?

Answer 1

n = 71

Explanation:

We take three consecutive numbers n-1, n and n+1.

the sum of this three is

n-1 + n + n+1 = 210 => 3n = 210 => n = 210/3 = 70

The largest of the three numbers is

n+1 = 70 + 1 = 71
