25+32+17=72

Answer 3

Let's denote the third number as "x."

According to the information given:

1. The sum of three numbers is 72.
2. The first number is 25.
3. The second number is 7 more than the first number.

So, we can write down the equations:

1. x + 25 + (25 + 7) = 72

Now, let's solve for "x":

1. x + 25 + 32 = 72
2. x + 57 = 72
3. x = 72 - 57
4. x = 15

Therefore, the third number (x) is 15.
