Question

There are the consecutive number. First and third number is 72 .find the middle number.

Answer 1

Nope, I can't.

First of all your statement does not make any grammatical sense and your spelling is atrocious.

Secondly, consecutive numbers are integers that are one unit apart.
So algebraically your three numbers would be
x, x+1, and x+2

then x = x+2 = 72, which has no solution.
