Question

Which term of the following sequences:

(a) (b) (c)

Answer 1

(a) The given sequence is

Here, a = 2 and r =

Let the n^th term of the given sequence be 128.

Thus, the 13^th term of the given sequence is 128.

(b) The given sequence is

Here,

Let the n^th term of the given sequence be 729.

Thus, the 12^th term of the given sequence is 729.

(c) The given sequence is

Here,

Let the n^th term of the given sequence be .

Thus, the 9^th term of the given sequence is .
