Hi, Thanks for helping! Could you help me find a simpler way to solve this? I think there is an equation you can use to solve a problem like this, but I don't remember it. Please help! :?

Problem: What is the 2003rd positive odd number?

Thanks again. I really do appreciate it.

What is an even number? Every even number is divisible by 2. so what is an odd number? one plus an even number, lol. so, we can say the n+1th odd number is 2n+1 where n is any natural number [0,inf) (it would be the n+1th odd number because when n=0 it is the 1st, n=1 it is the 2nd, n=x it is the x+1th)

so, 2002(2)+1=4005 which should be the 2003rd odd number

easier to go 2003*2 - 1 ; 2n - 1
