Answer: 2,147,483,648

Step-by-step explanation: Long number, but the pattern is to keep multiplying the previous number by 4

The 15th term of the geometric sequence 8, 32, 128.... is 2147483648

How to find the terms in a geometric sequence?

aₙ = arⁿ⁻¹

where

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

Therefore,

a = 8

r = 32 / 8 = 128 / 32  = 4

Hence,

a₁₅ = 8 × 4¹⁵⁻¹

a₁₅ = 8 × 4¹⁴

a₁₅ = 8 × 268435456

a₁₅ = 2147483648
