purpose to right
Recursive:  f(n)=f(n-1)+/-/x/divide, any term
Explicit: f(n)=a term multiplied/divided/to a power by or of n

Recursive: a formula that lets you find the next number in the sequence

Explicit:  a formula that represents the Nth term in a sequence.

Sum of Sequence: the sum of all the numbers in the given number of stages of a sequence

Arithmetic means: the average set of the numbers in a sequence, in a table you add the terms given together and divide by the number of times you go from one term to the next.

Geometric means:  constant change  found, in a table you divide the numbers given then root it by the number of jumps from one number to the next.
