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

Best ResponseYou've already chosen the best response.0All you need to do is to plug in both a and an and see which one is equal.

Best ResponseYou've already chosen the best response.0You find which one is the right one by trying every equation till you get both sides equal.

Best ResponseYou've already chosen the best response.1n 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

Best ResponseYou've already chosen the best response.1The 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.

Best ResponseYou've already chosen the best response.1None of the choices you gave represent the recursive rule. Also, the third and fourth choices in your post are the same.

Best ResponseYou've already chosen the best response.1Look at last choice. It's what I wrote. Look again at the pattern I wrote, and see how I arrived at choice #4
