Show that the product of two consecutive numbers cannot be a perfect square

[@Nayeem_5052]

Sir I have a prove that type question of Recurrence Relation that I am unable to solve, can u solve it and make a video on it. Question is : Given, F1 = 0 F2 = 1 F3 = 3 F4 = 4 Fn = Fn-1 + Fn-3 + Fn-4, for any natural number n >= 5 For example, F5 = F5-1 + F5-3 + F5-4 = F4 + F2 + F1 = 4 + 1 + 0 = 5 Prove that sqrt(F2p) = sqrt(F2p-2) + sqrt(F2p-4) for any natural number p >=3 . Can u please prove this, u can verify the question by checking the values till around F16, they will always follow this pattern.

Well I'm not familiar with recurrence relation now, but soon I'll learn and definitely will try to make a video on it. Thank you for your suggestion 😊
