Find the next two terms in the sequence.

9.8, 0.7, - 8.4, - 17.5, ...

-35, - 70

-26.6, - 35.7

26.6, 35.7

18.9, 28

Find the exact value of the eighth term of the geometric sequence:

648, 216, 72, 24 ...

.30

8/27

8/2481

8/9

Find the next three terms of the geometric sequence:

-3, 6, - 12, 24 ...

-36, 48, - 60

-34, 58, - 92

48, - 96, 192

-48, 96, - 192

The first one subtracts 9.1 - - > - 26.6, - 35.7

The second one subtracts 35 - - > - 105, - 140

The third one subtracts 9.1 - - > - 44.8, - 53.9

The fourth one adds 9.1 - - > 44.8, 53.9

The fifth one adds 9.1 - - > 37.1, 46.2

I am sorry I do not have time to do the rest, but just find a pattern between the given terms and apply that to the next terms

The first one is arithmetic with CD = - 9.1 so the answer is B

Third one is D

Second question:

a1 = 648 and r = 1/3 so 8th term = 648 * (1/3) ^7 = 8/27
