Answer: 24, Joshua is 24.
Explanation:
3 consecutive integers with a sum of a number that is divisible by 3 will guarantee that you can just divide by three, add 1 then subtract 1:
72/3 = 24
24 is one of the numbers.
24 - 1 = 3.
23 is one of the numbers.
24 + 1 = 25.
25 is the last number.
If you arrange them, they are consecutive:
23, 24, 25!
Joshua is 24. Check: 23 + 24 + 25 = 72! Correcto!
