Best ResponseYou've already chosen the best response.1However, I don't know how to put it in logic yet. Just use "try and error" method to find it out. It might have other solution but I didn't find it out yet.

Best ResponseYou've already chosen the best response.0i would say: \({a}{b}= n_1 +n_2 \cdots a=8\) where n are consecutive integers. So a + this integers must sum 8. Now just check which can match this.
