n + n + 1 = 57 2 n + 1 = 57 2 n = 57 − 1 2 n = 56 n = 2 56 = 28 n + 1 = 28 + 1 = 29
The two consecutive whole numbers whose sum is 57 are 28 and 29. The solution involves setting up an equation with the first number as n and the second as n + 1 . Solving the equation gives the two numbers as 28 and 29.
