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

So the sequence will be 4, 8, 16, 32, 64, 128 .......

Step-by-step explanation:

We have to graph the first six terms of a sequence with first term a = 4 and r = 2 Since r denotes common ratio so the given sequence is a geometric sequence.

Now we know the explicit formula for a geometric sequence is

Since   = 4

So         = 4 × 2 = 8

            = 4 × 2² = 4 × 4 = 16

            = = 4 × 8 = 32

            = = 4 × 16 = 64

            = = 4 × 32 = 128

So the sequence will be 4, 8, 16, 32, 64, 128 .......
