Note for OP
+solved @user to close the thread when your doubt is solved. Mention the user who helped you solve the doubt. This will be added to their stats.I proceeded by cubing both sides
$a_{n+1}^3 = a_n +60$
\newline
then i realized that $\lfloor a_1 \rfloor = 3$
Fermat's Last Theorem
even YOU need halp? 💀
c?
cube root is strictly increasing fn
cube root of a <= cube root of b if a <=b
even though the terms are increasing relative to each other, their gif will always be equal to 3
Oh thanks!
How do i mention this as solved
+solved
You need to mention a member to mark the thread as solved.
+solved @user. This will be added to their stats.didnt work kya?
with the mention
only op can do this
yeah true i forgot my own code lmao
ill make a thing jisse it will ask the op
How would we conclude that?
induction
a_1 < 4
a2= cube root of smth less than 64 so a2 is less than 4
similarly a3<4
