The common ratio of the geometric sequence is 3 / 4

How to find common ratio?

The common ratio of a geometric sequence can be found as follows:

a(n) = arⁿ⁻¹

Therefore,

  • a = first term
  • n = number of terms
  • r = common ratio

Therefore,

16 = ar¹⁻¹

16 = a

Hence,

12 = 16r²⁻¹

12 = 16r

r = 12 / 16

r = 6 / 8

r = 3 / 4

Therefore, the common ratio is r = 3 / 4
