Graph the first six terms of a sequence where a1 = 2 and r = 4.

We are given with

a1 = 2

r = 4

These are components of a geometric series. The first term is 2 and the common ratio is 4. To get the first six terms, we use the formula:

an = a1 r^ (n-1)

a1 = 2 (4) ^ (1-1) = 2

a2 = 2 (4) ^ (2-1) = 8

a3 = 2 (4) ^ (3-1) = 32

a4 = 2 (4) ^ (4-1) = 128

a5 = 2 (4) ^ (5-1) = 512

a6 = 2 (4) ^ (6-1) = 2048
