[@madhav3444]

Strange function me pattern notice kiya tha even i ke liye f(i) - x 2 - 3 4 - 3 6 - 4 8 - 3 10 - 3 12 - 5 Then 14 se lekr 24 ke liye same pattern aayega, odd ke liye toh 2 hi hoga, but ye kaam nhi kr rha hai aisa kyo?

[@yashjain3407]

Take i=60, your method will take x=5 but its wrong.

[@madhav3444]

@@yashjain3407 hmm got it, thanks bro

[@anasali3448]
