Exercise- 5.2 Question No. 11 :

Which term of the A.P. 3, 15, 27, 39, … will be 132 more than its 54th term?

Class 10 Exercise 5.2 Question No. 11 Solutions

Given A.P. is 3, 15, 27, 39, …
= 3
d = a2 − a1 = 15 − 3 = 12
a54 = a + (54 − 1) d
= 3 + (53) (12)
= 3 + 636 = 639
132 + 639 = 771
We have to find the term of this A.P. which is 771.
Let nth term be 771.
an = a + (n − 1) d
771 = 3 + (n − 1) 12
768 = (n − 1) 12
(n − 1) = 64
n = 65
Therefore, 65th term was 132 more than 54th term.
