HELP!!
n an
1 4
2 12
3 28
4 60
Which recursive equation represents the pattern?
an = an – 1 + 2n
an = an – 1 + 2(n + 1)
an = an – 1 + 2n + 1
an = an – 1 + 2n + 1

All you need to do is to plug in both a and an and see which one is equal.

12  4 = 8 28  12 = 16 60  28 = 32 Why are the third and fourth choices equal?

You find which one is the right one by trying every equation till you get both sides equal.

Are some n's and (n1)'s subscripts and exponents?

n an 1 4 2 12 4 + 8 4 + 2^3 3 28 12 + 16 12 + 2^4 4 60 28 + 32 28 + 2^5 Do you see a pattern? Each term, an, is obtained by adding the previous term to 2 to the power n + 1

The way you wrote the choices makes no sense. There must be some exponents and subscripts there. You wrote everything as if it were simple numbers.

None of the choices you gave represent the recursive rule. Also, the third and fourth choices in your post are the same.

Look at last choice. It's what I wrote. Look again at the pattern I wrote, and see how I arrived at choice #4
