Determine if the sequence below is arithmetic or geometric and determine the common difference / ratio in simplest form.
4,12,36

Respuesta :

Answer:

Step-by-step explanation:

this is clearly not a linear sequence (the terms don't have the same difference).

so, it has to be a geometric sequence.

the common ratio is r.

s2 = s1 × r

16 = 64 × r

r = 16/64 = 1/4

control :

s3 = s2×r

4 = 16 × 1/4 = 4

correct.
