Let’s denote the first odd number as “x.” Since the numbers are consecutive odd numbers, the second odd number would be “x + 2,” and the third odd number would be “x + 4.”

According to the given information, the sum of the first two numbers is 96. Therefore, we can write the equation:

x + (x + 2) = 96

Simplifying the equation:

2x + 2 = 96

2x = 96 – 2

2x = 94

x = 94/2

x = 47

So the first odd number, x, is 47. The second odd number would be 47 + 2 = 49, and the third odd number would be 47 + 4 = 51.

Therefore, the third number is 51.
