Question

The sum of three consecutive integers is 78. What are the three integers?

Answer 1

The sum would be 25 + 26 + 27.

Answer 2

Answer: The three consecutive integers are 25, 26 and 27

Explanation:

Let the three consecutive integers be represented by n, (n + 1) and (n + 2)

The sum of the integers are therefore written as:

n + (n + 1) + (n + 2) = 78

3n + 3 = 78

Subtract 3 from both sides

3n = 78 - 3

3n = 75

Divide both sides by 3 to get the value of n

n = 75/3

n = 25

If n = 25, then n + 1 = 25 + 1 = 26 and n + 2 = 25 + 2 = 27

The three consecutive integers are therefore 25, 26 and 27.
