Your question should read "three consecutive numbers".

Well, without much ado, let's delve straight to the solution.

If the first number is x, then the second is (x + 1), and the third, (x + 2).

The three add up to 64.

x + (x + 1) + (x + 2) = 64.

Clear brackets.

x + x + 1 + x + 2 = 64.

Group like terms.

x + x + x + 1 + 2 = 64.
3x + 3 = 64
3x = 64 - 3
3x = 61

x = 20.3333 to 6.s.f

Check
20.3333 + 21.3333 + 22.3333 = 63.9999, which is VERY close to 64, if you ask me.
