Question

find two consecutive positive integers whose sum is 72

Answer 1

Consecutive numbers are numbers which follow one another whose difference between two numbers is 1.

Let the first number be x.

The second number is :

x + 1

Their sum is 72.

x + x + 1 = 72

2x + 1 = 72

2x = 72 - 1

2x = 71

x = 35.5

35.5 + 1 = 36.5

The two numbers are :

35.5 and 36.5
