#4’s answer is 108, if you look there is 6 of those. Therefore the total is about 743! No one validates these answers, not even the author?

Messed up on number 8. But it was a good quiz.

I just saw that there are 6 of the 18s. You are correct it should be 743. Sorry for my earlier reply. 😊

It increased by 5 each step. 50+55+60+65+70+75+80+85+90+95=725
