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+(n1)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+(n1)d] y = last term, d = common difference, n = number of terms, a = first term of the sequence, S = sum of the first nterms 


Term

Definition
a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed nonzero number called the common ratio 


Term
The Nth or Last Term of a Geometric Sequence 

Definition
n=a(r^(n1)) r common ratio n  number of terms a  first term of the sequence 


Term
The Sum of the First Nterms of a Geometric Sequence 

Definition
s=(a(1(r^n)))/(1r) r  common ratio n  number of terms a  first term of the sequence S  sum of first nterms
