@jimmysmith560 Is it necessary to write the long final conclusion statement, especially when we are doing a test or can we suffice by just writing "as per mathematical induction the following statement is true for ...."
I'm not jimmy, but can help you out here. Honestly, I would stick to what your school tells you to do. With me, I had asked my teacher (as well as other teachers) before exams, and they said it was fine to write a small conclusion, as in theory, it doesn't test your understanding of the topic (but some schools may assign a mark for completeness). So I could get away with a conclusion like "Thus, according to mathematical induction, 2^x - 1 will always be prime for all odd numbers x > 1" (just a hypothetical example).
TL;DR --> ask your teacher for what is acceptable; different schools will have their own way
