B.sequences

To find the value of the nth term in an arithmetic sequence, use the following equation:

an = a1 + (n�1)d

a is the standard variable used to represent a term in a sequence and n counts the term number, so an represents the term in the sequence that you�re trying to find. d is the constant. To solve the problem, just substitute 101 for n, �3 for a1, and 5 for d.

a101 = -3 + (101 � 1)5
a101 = 497 part B
