Question

The sum of three consecutive integers is
45. Find the value of the middle of the three.

Answer 1

15

Explanation:

Let x, x+1, and x+2, be the three consecutive numbers.

x+(x+1)+(x+2) = 45

3x + 3 = 45

Divide both sides by 3,

x + 1 = 15

x = 14

Hence, the given three consecutive numbers are 14, 15 and 16.
