Which of the following is a Recursive Formula for an Arithmetic Sequence? a1 = -3, an = an-1 + 6
an = -3 + 6(n – 1)
a1 = -3, an = 6an-1
an = 6n – 9

The great thing about this problem is they give you everything you need to solve it easily. so the expression is: 12h+30w12h+30wand so everywhere you have an “h” you place 66. and everywhere you have a “w” you place 33. then the expression will look like this: 12(66)+30(33)12(66)+30(33)from here you multiply and then add. getting the following of: $785,862hope this
