200

Find the 5th term in the following sequence (show or explain your work: 

f(n) = f(n-1) * 3, f(1) = 5, n>1

Start at 5 and multiply by 3 until you reach 5th term: 5, 15, 45, 135, 405

405 

300

Is the following sequence geometric, arithmetic, or neither? Show or explain your reasoning


Geometric, growth factor of 6

300

Define the sequence displayed in the graph below for the nth term: 

f(n)=3(2)^n, n>=0

or f(n)=3(2)^(n-1), n>=1

300

Write the recursive definition of the following sequence: 5, 20, 80, 320, ...

f(n) = f(n-1) * 4, f(1)=5, n>1

1536

400

Is the following sequence arithmetic, geometric, or neither: 

f(n) = f(n-1)/2, f(1)=7, n>1

Explain your reasoning 



Geometric, dividing by the same number over and over same as multiplying by 1/2 over and over

400

A sequence can be defined recursively by the following: 

f(1) = 8, f(n)= 3*f(n-1), n>1
