Question

Please help! Find the third term of the sequence a_1=12, a_(n+1)=(a_n)/(n+1

Answer 1

Is this an AP? That thing you wrote for the nth term seems odd - could you check that out please?

Answer 2

Hmm... Yes, it's the problem word for word. :/

Answer 3

Can you help or does it not make sense? :/

Answer 4

well,
\[a_n = \frac{a_{n-1}}{n}\]and \[a_1 =12 ~~\rightarrow given\]

so, \[a_2 = a_1/2 = 12 /2\]
and hence, \[a_3 = a_2/3\]


helps?
