Answer:

17

Step-by-step explanation:

since it is in the middle you can just divide by 3 since one will be greater and one will be less so 51/3=17
Assume the second number to be x, then the first numbers is X-2, third number is x + 2
Thus we have a sequence of x-2,x,x+2,the sum of these number is 51:
X-2+x+x+2=51
X=17
So, 15, 17, 19
