Question

18. The sum of two consecutive odd numbers is 72. Find the numbers.

Answer 1

35 and 37

Explanation:

The difference between 2 consecutive odd numbers would be 2 so you can use the equation :

x + (x+2) = 72

2x + 2 = 72

2x = 70

x = 35

Then plug that back in to x+2 to find the other odd number:

35 + 2 = 37

So the numbers would be 35 and 37.

Another way could have just been to divide 72 in half which is 36, then choose the odd numbers below and above it, which would be 35 and 37.
