Find the sequence of the numbers defined...

Find the sequence of the numbers defined by
`a_(n)={{:(1/n,"when n is odd"),(-1/n,"when n is even"):}`

Text Solution

Verified by Experts

Using `a_(n)=1/n,` we have
`a_(1)=1,a_(3)=1/3,a_(5)=1/5`,…
Using `a_(n)=-1/n`, we have
`a_(2)=-1/2,a_(4)=-1/4,a_(6)=-1/6,…`
