Question

The nth term of G.P is 3(0.3)^n - 1, then find the common ratio​

Answer 1

Answer:

A Geometric Progression is of the form:

a_n = ar^{n-1}a

n

=ar

n−1

where a is the first term and r is the common ratio.

here, the given GP is:

a_n = 2 \times (0.5)^{n-1}a

n

=2×(0.5)

n−1

Comparing with the standard form,

common ratio = 0.5

Answer 2

Answer:

0.3

Step-by-step explanation:

nth term = 3(0.3)^n-1

ar^n-1= 3(0.3)^n-1

a=3 & r=0.3
