Question

A sequence can be generated by using an=4an−1, where a1=7 and n is a whole number greater than 1.

What are the first 3 terms in the sequence?

4, 28, 196
7, 28, 112
4, 11, 18
7, 11, 15

Answer 1

Answer: 7, 28, 112

Step-by-step explanation: The first three terms in the sequence can be found by using the formula an = 4an-1, starting with the initial value a1 = 7:

a2 = 4a1 = 4 * 7 = 28

a3 = 4a2 = 4 * 28 = 112

So, the first three terms in the sequence are 7, 28, 112.
