Subject: Number Sequences Name: Justin Schessler Who is asking: Student Level: Middle
Question: I CAN NOT figure out this sequence or how we continue this sequence... 3,2,6,5,15,14,___,___,___ Can you PLEASE help me ?
Thank You, ps. my dad said this site might be a real help. Hi Justin, Sometimes these number or letter sequence problems are obvious like
sometimes they are bizarre like O, T, T, F, F, S, S, __, __, ...
and sometimes there is more than one set of rules that will generate the terms you have.
I don't see anything obvious and I don't recognize it as one of the more bizarre examples I have seen. The only pattern I see is: - every even numbered term, (2, 5, 14) is one less than the previous term
- the first odd numbered term is 3 and after that each odd numbered term is 3 time the previous term.
- the seventh term is 3*(the sixth term) = 3*14 = 42
- the eighth term is one less than the seventh term, 42 - 1 = 41
- the ninth term is 3*(the eighth term) = 3*41 = 123
This may not be the sequence that is sought, but it consistently explains the first 6 terms.
Cheers,
By the way the letter sequence above in made from the first letters of the counting numbers, |
