During the end of this week in math we learned about arithmetic sequences.  Its a way of taking a pattern of numbers and finding the rule, this way we can find any term in the sequence.

If we are given 3,13,23,33 we can see the sequence is going up by 10 each time.  These are the first 4 terms, we can use this information to get too the 50th term for example.

We know that t1 is 3….t2 is 3+10….t3 is 3+10+10, therefore t50 would be 3+49(because we want t50 and already have t1…50-1) 3+49(10)=3+490=493
