HSF.BF.A.2
Write arithmetic and geometric sequences both recursively and with an explicit formula, and translate between the two forms. Use arithmetic and geometric sequences to model situations.
Example Problems
Find the fourth term in the sequence.
Find the 8th term in the sequence.
Find the 16th term in the sequence.
