Standards: 1/24/18MGSE9-12.F.BF.1a Determine an explicit expression and the recursive process (steps for calculation) from context.
MGSE9-12.F.BF.2 Write arithmetic sequences recursively and explicitly, use them to model situations, and translate between the two forms. Connect arithmetic sequences to linear functions.

Notes (INB)A sequence is an ordered list of numbers that has a constant difference between each term.• To find the nth term in a
number series, use an = a1 + (n-1)d (explicit)
nth term 1st term # of terms common difference
