Let's solve the world's math problems!
Write a recursive formula for the sequence 15, 26, 48, 92, 180,.... Then find the next term
- Click and drag over the problem to make highlights.
- Type the next step in the solution to this problem.
- Keep the math beautiful by using [[ and ]] around spans of math.
- Don't do x^2. Instead do [[x^2]] to get x2, etc.
Step 1: 48 is twice 26, then subtract 4. 92 is twice 48 then subtract 4, 180 is twice 92 then subtract 4.
Step 2: so if you are on number n, you can get to the next number by doing 2n-4.

I know how to do a lot of math, maybe I can help:
