a1  = 9 and the common ratio is 6.

Answer 1

Question :
Find the formula for the 19th term of the sequence in which a1 = 9 and the common ratio is 6.
Answer :
From the question we know that :
n = 19th
a₁ = 9
r = 6
General Formulas To find any term of a geometric sequence:

`a_(n)=a_(1) \cdot r^((n-1))`

The formula for the 19th term of the sequence :

`a_(19)=9 \cdot 6^((19-1))`


`a_(19)=9 \cdot 6^(18)`
