Can someone post theory/more problems related to this questions from sum of binomial series


Q7

I have written this approach in my old notes which I can't find right now

As far as I can remember there were many case like

  1. sum of upper term of ncr remain constant
  2. sum of lower term of ncr remain constant
  3. difference of upper term of ncr remain constant
    Etc.

These types of problems

Sorry to disappoint you but you should try yourself to search for questions like that.
I have seen your threads you rely too much on others come on do some hard work, if you search for those questions yourself , then your ability to distinguish questions based on different concept
will also shine.

Just a advice from my side !!
