Answer 1

Let three consecutive numbers be x, x+1, x+2.

So middle number is x + 1.

According to the question,

x + ( x + 1 ) + ( x + 2 ) = 51

3x + 3 = 51

3 x = 51 - 3

3 x = 48

x = 48 / 3

x = 16

Middle number = x +1 = 16 + 1.

=> 17.

Answer 2

Let these integers be y , (y+1), (y+2)

A.T.Q

y+y+1+y+2=51
3y+3=51
3y=51-3
3y=48
y=48/3
y=16

Middle no. =(y+1)= 16+1=17
