Will mark brainliest! in a geometric sequence {an}, if a1 = 4 and r = 0.2, the first 4 terms in the sequence a) {4, .8, .16, .}. b) {4, 20, 100, }. c) {4, 4.2, 4.4, 4.}. d) {4, 3.8, 3.6, 3.}.

The first 4 terms in the sequence are...

A) {4, .8, .16, .032,...}.

Geometry sequence are series of numbers that have a constant ratio

or can be interpreted:

Each number is obtained by multiplying the previous number by a constant

The sequence can be:

a, ar, ar², ar³, ... etc.

Can be formulated

where:

a is the first term, and

r is the common ratio

In an geometric sequence , if a1 = 4 and r = 0.2, the first 4 terms in the sequence are

i think it is 18

step-by-step explanation:

22.83 repeating

step-by-step explanation:

137 ÷ 6 is 22.8333333 therefore we understand that 3 is repeating.

happy to

pls mark as brainliest
