if the question had T_n = 3T_{n+1} - 2T_{n+2} - 1 instead of T_n = 3T_{n-1} - 2T_{n-2} - 1, would we use n>=k instead of n=<k
also why do we need the '>' and '<' sign and not stick with n=k like in normal induction
Hi all,
Need help with 'strong' induction, a few questions on this topic in cambridge but they don't provide examples so im not sure how it differs from normal induction (n=1, n=k, n=k+1).
Any help is appreciated.
Example below:

11) Suppose that OABC is a parallelogram. Let M be the midpoint of OA and let P be the point of intersection of MC and OB.
Prove using vectors, that: OP = (1/3)*OB
Hi Mathematicians,
I need help on question D, i think it's impossible to solve.
Question asks: a 5 digit number is chosen at random. Find the probability:
d) that the digits are distinct and in increasing order.
Good luck!
ok i get this but the thing is where did you pull this equation from
what is the formula for odd polynomial or even polynomial for degree 2, 4, 5 so on...
