Let the integers be x, (x+1) and (x+2).
The middle one is (x+1)
So, your equation will be:
x + (x+1) + (x+2) = 51
or, 3x + 3 = 51
or, 3x = 51-3
or, 3x = 48
or, x = 48/3
or, x = 16
The middle integer is 16+1 = 17
Hope it helps you.

Let the three consecutive numbers are x-1, x, x+1.
according to question,
(x-1) + (x) + (x+1) = 51
or, 3x = 51
or, x= 17
therefore numbers are 16, 17, 18
And middle one is 17.
