Recursive Formula Geometric Sequences

The next two terms of the sequence 2,-4, 8,-16 are

• 32, 64

• 32, -64

• -64, 108

• 32, 20

The recursive formula can only be used if you know the previuos term

• True

• False

The Recursive Formula for the Geometric Sequence is:

A formula that requires the computation of all previous terms to find the value of a_n.

• Explicit Formula

• Recursive Formula

• Arithmetic Formula

• Geometric Formula

Which recursive formula best describes the sequence
2, -6, 18, - 54... 

• a_n=a_n-1* -4, a₁ = 2

• a_n=a_n-1* - 8, a₁ =2

• a_n=a_n-1* 2, a₁ = -3

• a_n=a_n-1* -3, a₁ =2

Which of the following is the recursive formula for geometric sequences?

• g_n=g_n-1 (r)

• g_n=g₁ (r^n-1)

How do you write the recursive formula for geometric sequences using function notation?

• f(n) = f(n-1) * r

• f(n) = f(n-1) / r

• f(n) = f(n-1) + r

• f(n) = f(n-1) + r^n

What is the recursive form for the following sequence
3, 15, 75, 375, 1875...

• a_n= 5*a_n-1

• a_n= (1/5)*a_n-1

• a_n= a_n-1+5

• a_n= a_n-1 - 5
