Ive been looking at this problem and trying to use examples online to try to solve it but I get stuck.
It says to use mathematical induction to prove (1/1*4)+(1/4*7)+(1/7*10)+ ... + (1/(3n-2)(3n+1)) = n/(3n+1)
I solve for n=1 and substitute k for n, but I don’t really know what to do after that step.
It would really help to see this problem laid out step by step. Thank you!!
