Question

What is the 7th term of the geometric sequence where a1 = -625 and a2 = 125

Answer 1

first find the common ratio of the sequence - can you do that?

Answer 2

find the common ratio first of all...nd then find the seventh term

Answer 3

is it -500

Answer 4

no its not tht

Answer 5

the seventh term = a1*r^6 where r = common ratio

Answer 6

r = a2 / a1

Answer 7

what is the common difference

Answer 8

-5

Answer 9

common ratio = 125 / -625

Answer 10

-0.2

Answer 11

coomon differnce is a property of an arithmetic sequence
geometric sequence has a common ratio

Answer 12

common ratio means a2/a1

Answer 13

right

Answer 14

is the answer 0.04

Answer 15

-0/2 is correct for r

7th term = -625 * (-0.2)^6

Answer 16

125 / -625 = -1/5

Answer 17

so -0.04

Answer 18

* sorry that' s r = -0.2 or -1/5

Answer 19

yea

Answer 20

thank you guys!

Answer 21
