As the 7th term of an ap is 32
Acc. To formula
Tn = a + (n-1)d where n= no . of terms and a = first term d = difference between two terms
T7 = a + (7-1)d = a +6d. = 32. .....1
Similarly T13 = a + 12d = 62. .....2
Solving 1 and 2 we get d=5 and
A= 2so. The ap is
2,7,12,17,22,27,32,37,42,47,52,57,62,67, and so on
