Term
|
Definition
a sequence of numbers such that the difference of any two successive members of the sequence is a constant |
|
|
Term
The Nth Term of an Arithmetic Sequence |
|
Definition
y=a+(n-1)d a = first number in the sequence n = nth term of the sequence d = common difference. |
|
|
Term
Sum of an Arithmetic Sequence |
|
Definition
s=(n/2)(a+y)=(n/2)[2a+(n-1)d] y = last term, d = common difference, n = number of terms, a = first term of the sequence, S = sum of the first n-terms |

Term
|
Definition
a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed non-zero number called the common ratio |
|
|
Term
The Nth or Last Term of a Geometric Sequence |
|
Definition
n=a(r^(n-1)) r- common ratio n - number of terms a - first term of the sequence |
|
|
Term
The Sum of the First N-terms of a Geometric Sequence |
|
Definition
s=(a(1-(r^n)))/(1-r) r - common ratio n - number of terms a - first term of the sequence S - sum of first n-terms |
