CONTEST: Pentagonal Number Problem

Hey!

I have a little contest for my friends in Math Seminar. I reshared a problem called "Pentagonal Number". I couldn't get the answer. try figure it out! Whoever gets the answer first wins the contest and gets candy from me the next day school day. I'll also announce their win in a note if they wish. If you want to participate, let me know in Math Seminar tomorrow! Happy solving!

Note: This only applies to Thato Mthethwa's friends in Math Seminar.
