Hi guys,
the x's are supposed to be *, as in 2x2 is supposed to be 2*2, it won't listen to me.
I was wondering if it is possible to simplify this sequence:
[tex]1)2[/tex]
[tex]2)2^2 +4[/tex]
[tex]3)2^3 +(2 * 4) + 6[/tex]
[tex]4)2^4 + (2^2 * 4) + (2 * 6) +8[/tex]
[tex]5)2^5 + (2^3 * 4) + (2^2 * 6) + (2 * 8) + 10[/tex]
[tex]6)2^6 + (2^4 * 4) + (2^3 * 6) + (2^2 * 8) + (2 * 10) + 12[/tex]
I've made a few attempts but there are not satisfactory:
[tex]2^n + 2^n-2 * (n-(n-2))+2^n-3 * (n-(n-4))+...+2^2 * (2n-2) + 2^0 * 2n[/tex]
Any help appreciated
