Question

The formula for any geometric sequence is a n = a 1 · r n - 1 , where a n represents the value of the nth term, a 1 represents the value of the first term, r represents the common ratio, and n represents the term number. What is the formula for the geometric sequence 4, 8, 16, 32, ...?

an = 32 · 2n - 1
an = 2 · 4n - 1
an = 4 · ()n - 1
an = 4 · 2n - 1
