Answer 2

Here is your solution

Let,
The first odd integer be:x

Then the second odd integer is:-
x+2

Then the third odd integer is:-
x+2+2=x+4

Sum of three consecutive odd numbers =51

A/q

(x)+(x+2)+(x+4)=57
3x+6=57
3x=57-6
3x=51
x=17
now

The first integer is: x=17

The second integer is: x+2=17+2 = 19

The third integer is: x+4=17+4=21

Middle term is 19
