A1= -3, r =-2, 10th term

Question

What is the answer A1= -3, r =-2, 10th term

 

Answer 1

Formula for the General Term of a Geometric Sequence: the nth term

A_n = (A₁)(r)^(n-1)

 

Plug in the given values for A₁, r and n = 10 for the 10^th term

 

A₁₀= (-3)(-2)^(10-1)

A₁₀ = (-3)(-2)⁹

A₁₀ = (-3)(-512)

A₁₀ = 1,536

 

The 10^th term is 1,536
