6C ­ Arithmetic Sequences
Arithmetic Sequence: Adding or subtracting a given value to get the next term
Ex. 18, 15, 12, 9, ...
Common Difference (d) = These are like __________ FUNctions
(1, 18) (2, 15) (3, 12) (4, 9) ...
(d is like the gradient)

**nth term of an Arithmetic Sequence
un = nth term
u1 = 1st term
n = term number
d = difference
Ex. Write a formula for the nth term of the following sequence: 4, 7, 10, 13, 16, 19, 22, ...
What is the 33rd term of the sequence above?
