What I know about SAP, why SAP?

Puzzle a pattern, it was a pentagon, then 2nd one was two pentagons whose vertices were connected, every line between two points would be considered as a connection. How many connections would be there in the 75th pattern? I tried to solve and came to a recursive solution within 5 mins( Ans: 5(n)+number of connections in [n-1]the pattern). He said this recursive solution, how can u find without using a system, I explained him that all things we do are on system and clients would need a program for such a question and this would work fine, he was very much impressed.

He said he will choose a number between 1 to 200 , U have to write down a set of questions asking them u have to tell me the number and note that the same question should work if I change the range from 1000-2000. I started thinking, and then I thought a binary search would work in this case, I wrote related questions and said it’s a binary search he asked me to write a code for it.
