0 Guest Posted March 28, 2008 Report Share Posted March 28, 2008 (edited) 1. Double the previous term 2. Triple the previous term 3. +2, +3, +4, +5, +7... 4. +3, +5, +7, +9, +11... OR square each number, they're the same thing 5. f(n) = n3 6. f(n) = f(n-1) + f(n-2)... Think that's right.

0 Guest Posted March 28, 2008 Report Share Posted March 28, 2008 1)multiply each instance by 2 2)multiply each instance by 3 3)add 2, add 3, add 4, etc.. 4)square each instance 5)n^3 for each instance 6)add the preceding 2 instances together Very good, you are 100% correct. I hadn't thought about your answer for #3, but now that I am thinking about it, it works as well as mine did. Actually it's about the same answer in different forms. triangles As I said, very good... ...But can you name the 6th one? (it does have an official name) Quote Link to comment Share on other sites More sharing options...
