Question

Determine if the sequence below is arithmetic or geometric and determine the common difference/ratio in the simplest form 2,8,32,…

I need this filled out in this format;
This is a____ sequence and the common ratio/common difference(choose one) is equal to___

Answer 1

Notice:

2 is first term

2*4 = 8 is second term

8*4 = 32 is third term

and so on

Each term is multiplied by 4 to get the next term, so it’s geometric. The “common ratio” is whatever you’re multiplying by, which is 4.
