# Is it possible to create a fairly basic formula for this pattern?

I have this pattern: 14, 33, 40 Do you have any clue if it's possible to create a fairly basic formula for this? And with "fairly basic" I mean using only multiplication, division, subtraction, addition and power of.

If you figure it out, don't tell me the answer. Just tell me if it really is possible, and if so, give me a clue? Haha. Solving patterns is fun, and I'd really like to solve this one with my limited maths knowledge, I just need to know if it's possible yet! Any help would be awesome. Thanks.

This is my progress btw:
14 = 7+7
33 = 7+7+7+7+5
40 = 7+7+7+7+7+5

7(5+n) works for 33 and 40, but not 14!

• Three numbers aren't really enough to determine a pattern. Are there more in the sequence? – Alexis Olson Sep 30 '16 at 19:44

For $a_{0} = 14, a_{1} = 33, a_{2} = 40$, use: $${a_{n} \over a_{0}} = {n-1 \over 2} + 2.35714285714 \quad \mbox{for n = 1, 2, \ldots}$$
