Answer 3

lemme get the problem

Answer 4

\[\sum_{i=1}^{7}3(2)^{i-1}\]

Answer 5

is dis too complicated for your feeble minds? >:D

Answer 6

Take 3 outside \[\sum_{}^{}\]

Answer 7

Now find \[a_{1}\] by substituting 1 in i.

Answer 8

Then find \[a_{2}\]

Answer 9

Divide a2 by a1 to find r

Answer 10

i dont get it :/

Answer 11

Okay! I'll do it for you.

Answer 12

You are a lifesaver!

Answer 13

We have \[\sum_{i=1}^{7}3(2)^{i-1}\]

Answer 14

Take 3 outside.

Answer 15

so multiply ? what u mean take 3 outside?

Answer 16

\[3\sum_{i=1}^{7}(2)^{1-1}\]

Answer 17

Oh :P

Answer 18

So we have our first term after putting i=1.

Answer 19

Let it be a1. Our a1=3

Answer 20

Then plug i=2. We get 6. Let it be a2.

Answer 21

Now to find r, divide a2 by a1.

Answer 22

We get r=2

Answer 23

Getting it?

Answer 24

YESH.

Answer 25

Now we have a1=3, r=2 and our k=7

Answer 26

Use sum formula

Answer 27

Your answer will be 381
