# My $$50$$ followers note !

Here are a few challenging proofs to be done using Principles Of Mathematical Induction. I will be editing this note hereafter, by keeping new Induction Challenges, most probably one new challenge per week. Check these out and post your solutions in the comments below 📝 📬 📮 !

Challenge 1 -> Prove that the $$n^{th}$$ term in the Fibonacci series is :-

$$u_{n} = \dfrac {1}{\sqrt {5}}\left[ \left (\dfrac {1+\sqrt {5}}{2}\right) ^{n}-\left( \dfrac {1-\sqrt {5}}{2}\right) ^{n}\right]$$

Challenge 2 -> Prove the rule of transitivity in inequalities using only the definitions and induction principles.
