## anonymous one year ago Find the first six terms of the sequence. a1 = -7, an = 2 • an-1

1. Nnesha

we did it yesterday right ?

2. anonymous

It's not the same problem. I'm just confused with these types.

3. Nnesha

same method $\huge\rm a_n=2 \times a_{n-1}$ n= term that you need a_1 first term

4. Nnesha

to find 2nd term replace n by 2 $\huge\rm a_2=2 \times a_{2-1}$

5. anonymous

Ok...so would this be right? -7, -14, -28, -56, -112, -224

6. Nnesha

yep
