Look at the sequence in the table. which recursive formula represents the sequence shown? a) a1 = 1, an = 3an-1 b) a1 = 2, an = 2an-1 + 2 c) a1 = 2, an = 4an-1 - 2 d) a1 = 2, an = 3an-1 - 4

Dean and karlene get paid to write songs. dean is paid a one-time fee of $20 plus $80 per day. karlene is paid a one-time fee of $25 plus $100 per day. write an expression to represent how much a producer will pay to hire both to work the same number of days on a song.
