3rd question in flowchart assignment

Can we use the formula that number n is a fibonacci number if either 5nn +4 or 5nn -4 is a perfect square or is there some other method?
If there is an alternative method to solve it then kindly share. Thank you.

hello @aayushitalwar02 yest you are right you can check for any number in the fibonacci series. lets take:5
then 5*(25)-4=121
and 121 is the square of 11 (Perfect Square).
So, yes this formula is right.
Happy Learning !!

Can you also please provide the solutions to the flowchart problems so that we can cross check whether what we’ve done is correct or not

Okay, no problem. Please send the solution for the Apple and Oranges puzzle because this puzzle has not been discussed in the videos
