Can you me? i have no idea what to do. so much!

Okay, So technically this is Calculus BC and we our asked to find the first 5 terms of the sequence. When doing anything relating to sequence or even series we must think analytically. AND, this is multiple choice and we know the first term in the sequence starts at 3, so D is out.

This is a Recursively Defined Sequence, therefore we find a[2] by plugging in the term of a[1], which is 3 , into a[n-1]. Then we find a[3] by plugging in the term of a[2], which was 2, into a[n-1]

Note: a[n] = a sub n

The Answer is A: 3,2,0,-4,-12

The correct answer is 10%
