Tough math problemI'm having a really tough time solving this problem and could use some help! #2 20070419 07:09:37
Re: Tough math problemIt’s an iterative problem: where a_{n} is the number of oranges Shomika has left after giving to the nth person, and a_{3} = 10. So you just work backwards and find a_{0}. (a_{0} = 122.) PS: Last edited by JaneFairfax (20070419 07:35:37) #4 20070420 00:41:16
Re: Tough math problemThat’s exactly my method above. I like to generalize.
