Question 738790
I do not know a formula way to find this answer, and therefore cannot tell you the formula for the nth term.<P>
But finding the first term to reach 100 is easy.  List a few terms.  You'll see they quickly rise towards 100.<P>
-3, 0, 2, -1, 1, 2, 2, 5, 9, 16, 30, 55, 101 <P>
The 13th term reaches 100.
<P>Hope the solution helped.  Sometimes you need more than a solution.  Contact fcabanski@hotmail.com for online, private tutoring, or personalized problem solving (quick for groups of problems.)
