Hi!
I missed a math lesson last week and now I'm kinda stuck...
Even though all the needed formulae are in my math book, I've no idea how to solve the following problem:
A series is defined by a1 = 10 and an+1 = 4 + 2n - an and I must prove that the series formed by the odd members of the original series and the series formed by the even members of the original series both form arithmetic series with a difference of 2.
The members located in the odd and even places, that is.
So each number in the series is 2 greater than the number before the previous number.

So, every second number is 2 greater. Hence the odd places, or even places, follow the pattern.
