Are You Smarter Than A Third Grader?

Mirror, Mirror On The Wall

Whose The Smartest Of Them All

Will You Be Able To Crack The Code

And Prove You're Smarter Than An 8 Year Old?

Here is your problem of the week:

Given the following, find the pattern:

3, 4, 5

4, 7, 1

8, 4, 0

1, 2, 9

In the four examples given, the first two numbers were used to determine what the third number in the sequence was. 

Figure out how the third number in each sequence was determined (i.e. find the pattern).  

Here is a bit of interesting information.  It may help, it may cause you to over think it, and it may drive you downright nuts, but here it is:  the problem first appeared in a third-grade text!  (What math skills do third graders possess?)

Good Luck!  Answer will be posted Sunday!
