I'm stumped on this.. I don't remember this stuff and I need help. Not even sure it is in the right forum, but my Trig teacher gave us this on a worksheet so I tried my luck..
(Moderator - looked for a mod or admin online but none on to ask where to post this - please move to correct forum for me, if not in correct one.. thanks)
If x and n are positive integers with x > n and Xⁿ - Xⁿ⁻¹ - Xⁿ⁻² = 2009, find x + n.
A - 10
B - 11
C - 12
D - 13
E - 14
If anyone is able to answer this, can you explain how you got your answer so I can see what I should be doing here? I really appreciate it. Thanks..
