Answer:

34

Step-by-step explanation:

The formula for nth term of geometric sequence is aₙ = a₁.rⁿ⁻¹

Given, a₁ = 121 and a₃ = 64.

a₃ = a₁.r³⁻¹ = 121.r²

=> 121r² = 64

r² = 64/121

 r = 8/11

5th term of sequence = a₅ = a₁.r⁵⁻¹ = 121.(8/11)⁴

                                                          = 33.85 ~ 34
