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, .30 8/27 8/2481 8/9 find the next three terms of the geometric sequence: -3, 6, -12, -36, 48, -60 -34, 58, -92 48, -96, 192 -48, 96, -192

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

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
