Write an expression to describe the sequence below. use n to represent the position of a term in the sequence, where n = 1 for the first term. -3, -6, -9, -12,

Hello from MrBillDoesMath!

a(n) = -3n  , n>= 1

Discussion:

a(1) = -3

a(2) = -6

a(3) = -9

a(4) = -12

The pattern looks like a(n) = -3n

Thank you,

MrB

goog may have it for you
