Question

What is the sum of the geometric series
10
E 6(2)^n
n=1

I'm a little lost as to what I should do here. Could someone please clarify how this one is done?

Answer 1

You have a sequence with
a = 6*2^1 = 12
r=2
So, you have

S10 = 12 * (2^10-1)/(2-1) = 12276

Answer 2

Unit 4 Lesson 5 Geometric Series Alg 2 Connections
1.D No 6.D 165 11.C It converges; it has a sum.
2.D 0.972 7.A 1,365
3.A 12 feet 8.A 19.662
4.C 250 9.C 12, 276
5.A 10/sigma2n/n=1 10.A $138,037.53

Answer 3

1.D No
2.D 0.972
3.A 12 feet
4.C 250
5.A 10/sigma2n/n=1
6.D 10.A $138,037.53
7.A 1,365
8.A 19.662
9.C 12, 276
10.A $138,037.53
11.C It converges; it has a sum.
I made another one bc the first one was kinda confusing

Answer 4

^ same for honors except question 8 doesn't exist, so it's
