Sex - Women get it when they want. Men get it when they can

It depends on the sequence being summed. If we're summing $u_r = r$, then $u_0 = 0$, but if we're summing $u_r = r^2 - 2$, then $u_0 = -2$. Whether the 0th term exists depends on the sequence. Obviously it doesn't make sense to sum from 0 when the sequence starts from the r=1 term.

Understood this thanks.

Can I finally ask you what would you do if the term below the sigma read "r+1 (I assume this was a typo) and if the bottom said "2n" would you just do the same process although change the limits right?

Tip: Go for shy, slightly insecure men (not too insecure 'cos they're annoying). They can even be good looking if they were fat or really skinny as children/teens. They are likely to overcompensate in bed and try to please you. Hard.

Do you mean $\displaystyle\sum_{k=2n}^{r+1} a_k$ or something else? I'd just start from the lower limit, writing a few of the values of the sums(after finding the appropriate difference formula), then ... then the last few until the upper limit and look at what cancels, just like starting from k=1.
What do you mean by change the limits? You could shift the indices of the sequence like $\displaystyle\sum_{k=1}^{r +2- 2n} a_{k+2n-1}$, but this often doesn't achieve anything(for particular sums it's useful though).

That DJ-P0N3 shirt is boss, not gonna lie.

Lol no.

Maths a level is kids stuff :P

Further maths is easy too. Don't get too gassed.

Idd :P

That is why i am doing afm and step

AFM is even easier lol. The extra modules are pointless and often easier than FM. FP3 is easier than FP2 imo. m1, m3 and m4 are basic only m2 is hard. Better to do a proper subject than so much maths. You literally gain nothing fro doing loads of maths.

Biologically, the reasoning behind men and sex is primarily to reproduce. Therefore, a high sex drive allowed that. Now you look at it, we have 7.3 bil on the planet and don't need another 7.3 bil. Now, it's all about the pleasure that men get from it. (Not saying that is women don't get it...) but it's true.

Remember that the reason women reproduced was to have children too. But, in the case of a woman, she would be concerned about the baby's future. Was the father good looking enough for the child to have a good life? Was the father carrying anything that could be passed on? Etc...

Also, I do apologise for having fortunately upper class handsome friends. Just needed to address that issue. And you're wrong with your statement about how women don't face rejection. We really do! And there aren't that many good looking guys out there... I lie, but there aren't enough for every woman to have one... All of you men have a chance, so stop beating yourself up about it!

Lol! First and foremost, I am a woman. Second, the men who I have been with are truly amazing men. They are handsome and have more to offer than a d*ck. They also have a life and a personality. Which is also important

But your implication is that any handsome chap with a personality will not struggle in getting laid. That's simple false unless the girl(s) in question are not particularly desirable in any way. That might be true in that case.

The only way handsome men are going to get laid regularly and without struggle are a) super handsome, ie model looks, tall and buffed etc b) comes with wealth and status c) some other unique trait such as being an especially good charmer or something such as that.

That's if we are talking about pretty girls, girls who are obviously hot and desired and will have X amount of men at their pool of choice. Without a b or c no handsome man with a decent personality is going to get pussy on a plate... that's a ridiculous assumption tbh because that would imply that for any hot girl he fancies he can almost always bag her which is just not the case. A girl might have 10-20 guys she knows personally who she could just call and say 'come to my place' that she's not going to just **** any guy for the sake of it in the way a guy would. The only way a guy could attract any girl in such a way is through a b or c but not your regular decent chap whose handsome.
