Geometric Sequence

A number sequence formed by multiplying a term in a sequence by a fixed number to find the next term.

Explicit Formula for a Geometric Sequence

a_n= a₁ (r)^n-1

Multiple Choice

What does r represent in the explicit formula for a geometric sequence?

Radical

Common Ratio

Common Difference

Multiple Choice

Find the common ratio for the geometric sequence:

10,\ 20,\ 40,\ 80

1/2

Multiple Choice

Find the common ratio of the following geometric sequence

-250,\ -50,\ -10,\ 2

r = 5

r = -5

r = 1/5

r = -1/5

Multiple Choice

Is the following sequence geometric?

Yes

Multiple Choice

Is the following sequence geometric?

2,\ 4,\ 12,\ 48

Yes

Multiple Choice

$3,\ 24,\ 192,\ 1536$

Write the explicit formula for the following geometric sequence

$a_n=8\cdot3^{n-1}$

$a_n=3\cdot8^{n-1}$

$a_n=3+8\left(n-1\right)$

Multiple Choice

Which formula is the recursive equation for a geometric sequence?

a_1=

a_n=r\cdot a_{n-1}

$a_n=a_1+d\left(n-1\right)$

$a_n=a_1\cdot r^{n-1}$

$a_1=$
$a_n=d+a_{n-1}$

Multiple Choice

Write the recursive formula for the following sequence

16,\ 8,\ 4,\ 2

a_1=16

a_n=\frac{1}{2}\cdot a_{n-1}

$a_1=16$

a_n=2\cdot a_{n-1}

$a_1=16$
$a_n=a_{n-1}-8$

$a_1=16$

a_n=a_{n-1}+0.5

Multiple Choice

Given the recursive formula, write the explicit formula for the geometric sequence.

a_1=6

a_n=5\cdot a_{n-1}

$a_n=5\cdot6^{n-1}$

$a_n=6\cdot5^{n-1}$

$a_n=6+5\left(n-1\right)$

$a_n=5+6\left(n-1\right)$
