The sum of three consecutive numbers is 72. What is the middle number?
Mkey [24]

Answer:

48

Step-by-step explanation:

Assuming that the numbers went in a pattern instead of a random order it would be 48 because 48 divided by 3 would be 24. 24 would be the first number though, so it would be 48 because 24 plus 24 is 48.

Hope this helps, have a great day!
