Our formulas give the same sequence, bearing in mind you are looking at males and I am looking at the whole population, so my result x 2 = yours. Also our numbering is different. My index 1 is your 2.

You: 1 - (-1)^n / 3

n=1 1/2
n=2 3/12
n=3 9/24
n=4 0,3125
n=5 0.34375
n=6 0.328125

Me: num (d_n+1) =[ 2*num(d_n) + (-1)^(n+1) ]; den (d_n+1) = 2^(n+3); d_1 = 1

n=1 1/8 * 2 = 2/8
n=2 3/16 * 2 = 6/16
n=3 5/32 * 2 = 0.3125
n=4 11/64 * 2 = 0.34375
n=5 21/128 * 2 = 0.328125....etc.

Our recurrences can probably be shown to be the same but I think this is enough. I compared my sequence with the computer's result for d and it is the same.
