The sum of two consecutive whole numbers is 57. What are the two numbers?

Question

Let n represent the first number. Then let n+1 is the next consecutive whole number

Answer 1

A sum is the result of addition

 

n + n + 1 = 57        combine like terms

2n + 1 = 57            subtract 1 from both sides

2n = 56                   divide both sides by 2

n = 28

 

The two numbers are 28 and 29.
