Question
Find the fifth term and the nth term of the geometric sequence whose initial term $a_1$ and common ratio $r$ are given.$$a_1=2 ; \quad r=3$$
Step 1
The nth term \( a_n \) of a geometric sequence can be found using the formula: \[ a_n = a_1 \cdot r^{n-1} \] where \( a_1 \) is the first term and \( r \) is the common ratio. Show more…
