Answer:
   First term(a)=16
  7th term = 5th Term + 12
In A.P , common difference is always equal.
Let common difference =d
and 5th term = x
therefore ,
7th term = x+12 -----ist
also , 7th term = 5th term +d+d  --- 2nd 
from ist and 2nd , we get 
x+12 = x+2d
or 12 =2d
or d=6
therefore ,
2nd term in A.p = a+d =16+6 =22
3rd term = a+2d = 16+2*6 =16+12=28 
and  7th term =a+6d =16+6*6=16+36 =52

Hence the A.p will be 16,22,28,34,40,46,52
