How do you write the nth term rule for the sequence #1, 3, 5, 7, 9, ...#?
This is clearly an arithmetic sequence because the terms differ by 2 each time.
To find the nth term rule we need:
a value for the first term , a
and a value for the common difference d .
These values are then plugged into the formula:
This is the sequence of the odd positive integers where the
