Is this acceptable in recursive formulas?
Say for the recursive formula 2, 5, 9, 19 , 37...
Instead of writing it as an = an-1 + * 2 an-2 can you write it as: an = 2an + (-1)n Just double checking. I encountered this earlier helping someone and I haven't done recursive formulas in a while.. |

I think you meant an = 2an-1 + (-1)n
Sure. Your formula is the same as an = an-1 + (-1)n + an-1 = an-1 + (-1)n + 2an-2 + (-1)n-1 = an-1 + 2an-2 |
