In the sequence 3,8,13,18, what term of the series is the number 2218?

This is a sequence (not "series" unless they are
added together, with + signs between).

Note that the 2nd term - 1st term = 8-3 = 5

Note that the 3rd term - 2nd term = 13-8 = 5

Note that the 4th term - erd term = 18-13 = 5

That tells us that this is an arithmetic sequence 
with common difference, d=5.

The formula for the nth term  of an arithmetic
sequence is







Divide both side by 5





So , the 444th term.
