Change the information into an equation and do sequence. pull out any necessary information. y = 2x + 1 starts at 1... so your first sequence is 1. plug in x=1 then it becomes 3. then the next sequence you plug in 3 (, the answer to your previous solve) you get 7. continue to do this. next sequence you plug in x=7 into the equation y = 2x + 1. thus, y = 2(7) + 1 =15... so forth... therefore the answer is B.
