Andrea gave 1 widget and received 3; Brian gave 3 widgets and received 13; and Chris forgot how many widgets he gave,
but he received 28. Dan's conjecture was that the pattern was linear, which was verified when he gave 4 widgets. How
many widgets did Dan receive, and how many widgets did Chris give? Show all of your steps required to complete the
problem. Explain your reasoning and what you did to solve the problem. Turn in any scratch work you did into the In Bin
