Answer:

The two numbers are 84 and 85

Explanation:

13^2 = 169

So let the first consecutive number = x

Let the second consecutive number = x + 1

13^2 = 13*13 = 169 Develop the equation

x + x + 1 = 169 Combine Like terms on the left

2x + 1 = 169 Subtract 1 on both sides.

2x = 169-1 Combine the terms on the right

2x = 168 Divide by 2

x = 168/2

x = 84
