Sequence

1 / 24

25 Terms

1

Sequence

an ordered list of numbers, with each listed number being a term. It could be finite or infinite.

New cards
2

Arithmetic Sequence

when each successive term in a sequence has a common difference (constant rate of change).

New cards
3

Geometric Sequence

when each successive term in a sequence has a common ratio (consistent proportional change).

New cards
4

Linear Function

if the output values of a function change at a constant rate.

New cards
5

Exponential Function

if the output values of a function change at a proportional rate.

New cards
6

Nth Term (Arithmetic)

the formula to find the nth term in an arithmetic sequence.

New cards
7

Nth Term (Geometric)

the formula to find the nth term in a geometric sequence.

New cards
8

Exponential Functions

always increasing or always decreasing, with no extrema or inflection points.

New cards
9

Horizontal Translation/Vertical Dilation

shifting or scaling an exponential function.

New cards
