Question

which term of the AP : 3, 15, 27, 39,,... will be 132 more than its 54th term .​

Answer 1

Step-by-step explanation:

a = 3

d = 12

let the no of term be x

xth term = 132 + 54th term

a + (x-1)d = 132 + a + 53d

3 + (x-1)12 = 132 + 3 + 53(12)

(x-1)12 = 12(11 + 53)

so, x-1 = 64

so, x = 65
