Question

Find the next two terms in the sequence.

Answer 1

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

Answer 2

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
