1. ## Logistsic Recurrence Sequence

Hence

I don't see how.

2. You can derive it from the last statement

(E-Q_{n+1})-(E-Q_n) = Q_n - Q_{n+1}

Hence, if

(1 - \frac{E-Q_n}{E}) = (\frac{Q_n}{E})

the conclusion is correct. If you split the first part in

(1- \frac{E}{E} + \frac{Q_n}{E})

you'll see this is the case.

Something seems wrong with either my latex or the forums compiler, so i'll leave it this way.

Hope this helps.
