Question

Hiii. Please help. Will mark brainliest if correct!

Answer 1

Answer:

• C. aₙ = 9*(2/3)ⁿ⁻¹

Step-by-step explanation:

Given:

• The first term is a = 9 and the common ratio is r = 2/3.

The equation for the nth term of the GP:

• aₙ = a*rⁿ⁻¹

Substitute the values to get:

• aₙ = 9*(2/3)ⁿ⁻¹

Correct choice is C

Answer 2

Step-by-step explanation:

We know that

$\sf a_{n} = a \times r {}^{n - 1}$

$\sf \: a = 9(given)$

$\sf \: a_{n} = \frac{2}{3} ( a_{n} - 1)$

Putting = 9

$\sf a_n=9•\bigg(\dfrac{2}{3}\bigg)^{n-1}$
