Select all of the true statements about the sequence 11 112

Select all of the true statements about the sequence.

-11, -11.2, -9.4, -5.6, 0.2,...

a.) the sequence is geometric

b.) the common difference is -0.2

c.) the sequence is not geometric

d.) the ratios are not constant

-11, -11.2, -9.4, -5.6, 0.2, .....

Sequence will be geometric if

a1/a2 = a2/a3 = a3/a4

11/11.2 = 11.2/9.4 = 9.4/5.6

Since the above equatin is not equal, this sequence is not geometric.

Also, we can see that ratio is not constant

Correct options are = C and D
