Question

How do I solve this ? change a26 to a9

Answer 1

a₉ = 13122

Step-by-step explanation

The nth term of a geometric progression is given as

`a_n=a(r^(n-1))`

where

a = a₁ = first term = 2

r = common ratio = 3

We are then asked find the 9th term of this sequence

n = 9

`\begin{gathered} a_n=a(r^(n-1)) \\ a_9=2(3^(9-1)) \\ a_9=2(3^8) \\ a_9=2(6561) \\ a_9=13122 \end{gathered}`

Hope this Helps!!!
