Binomial Theorem, i got a note in my theory notes saying its testable i.e. they can ask to prove Tk+1/Tk=n-k+1/k*b/a. But how likely is it to happen?

use the general rule formula T(rplus1) over Tr.

then keep simplifing

its in any textbook

Its not that hard, just use definition of nCr. I think if they ask you to find the greatest coefficient of a binomial expansion, u can usually just use the formula

T(k+1)/T(k) >= 1
n-k+1/k*b/a >= 1
