97. CUT NUMBERS
Do you know that the number 6 has the following peculiar property?Add all the numbers before 6, namely 1+2+3+4+5=15. Add two consecutive numbers after 6. You get 7+ 8=15. In the natural sequence of numbers 6 balances (like a fulcrum) all the numbers before it with certain consecutive numbers after it. We call such a number a 'cut number’. The question is: What is the next higher cut number?
