Ageometric sequence is shown below: 66 a0, -11, 22, 56 a1, 88, -176. a) what is the common ratio for this geometric sequence? 69 a2 b) what are the missing terms in the geometric sequence shown above?

Step-by-step explanation:

Given a geometric sequence as

66 a0, -11, 22, 56 a1, 88, -176

We have to find the common ratio and also the missing numbers.

A geometric sequence, is a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio.

Hence by comparing two consecutive numbers let us find common ratio.

Consider 88 and -176.  -176 = 88(-2) Hence common ratio is -2

a0 = -11/-2 = 5.5

a1 = 88/-2 = -44

Missing terms are -132 and 5.5

common ratio = -2

a. -0.3 > -0.33

126 maybe. sorry
