Find the first six terms of the sequence.

a1 = -1, an = 2 • an-1

The first six terms of the sequence are: -1, -2, -4, -8, -16 and -32

Step-by-step explanation:

The sequence is:

So, for finding the first six terms of the sequence, we need to replace n by the numbers 1 to 6 and we get:

That means that the term n is 2 times the last term. Then, replacing the values of and , we get:

So, The first six terms of the sequence are: -1, -2, -4, -8, -16 and -32
