Best ResponseYou've already chosen the best response.0OK look at the difference between the consecutive numbers in the sequence. How much between 8 and 9? How much between 9 and 26? Do you see a pattern?

Best ResponseYou've already chosen the best response.0Good. So your rule "a" will look like: a = 17n + b where n is the "nth" term in the sequence b is some number. To solve for b, take the first number in the sequence (n=1, 1st number). When n=1, a=8. So: a = 17n + b 8 = 17*1 + b Can you solve for b?

Best ResponseYou've already chosen the best response.0Umm... I'm not really sure.  8 = 17*1 + b =  8 = 17 + b. subtract 17 from both sides?  25 = b?
