It should be A)
Bacali,
Friendly request: Please make sure you include the signs correctly in the problem
a ^ n = 2 * a ^ (n-1) - x is a whole lot easier to read and understand what the problem is really referring to. We can figure it out but sometimes assumptions can bite u in the back when providing solutions..
Also please incldue the official answer iusing SPOILER function.
Eg: [spoiler]OA:WHATEVER THE OA IS[/spoiler]
Regards,
Cramya
