im having problems in sequence questions :/

NotAbod:
replace n with any term, use first or second or anyone, doesnt matter.
i will choose the second term

3 = 2(2+1)/k
k = 6/3
k = 2.

or with the third term
6 = 3(3+1)/k
k = 12/6
k = 2

ABod i was about to say that.. :P

Shahtaj try understanding question because they are mostly twisted and if you don't then it won't be good :)

this question had nothing to do with sequence actually.
its all about algebra and substituting values.
