Question

The product of two consecutive odd integers is 195. Find the larger number.

Answer 1

The larger number is 15.

Explanation:

Call the first number x. The second number would be x+2.

x (x+2) = 195

x^2 + 2x = 195

There are a few ways to solve this problem. The simplest is that you can graph this and see that the positive x intercept is 13. So the 2 numbers would be 13 and 15.

13 x 15 = 195
