Write the first five terms of the sequence and obtain the corresponding series : `a_1=-1,a_n=(a_(n-1))/n ,ngeq2`

Text Solution

Verified by Experts

`a_1=-1` ,` a_n=a_(n-1)/n`
Putting `n=2`
`a_2=a_(2-1)/2`
`a_2=a_1/2`
`a_2=-1/2`
Putting `n=3`
`a_3=a_(3-1)/3`
`a_3=a_2/3`
`a_3=-3/2`
Putting `n=4`
`a_4=a_(4-1)/4`
`a_4=a_3/4`
`a_4=-12/2`
`a_4=-6`
Putting `n=5`
`a_5=a_(5-1)/5`
`a_5=a_4/5`
`a_5=-6/5`
Hence first five terms are `-1,-1/2,-3/2,-6,-6/5`
Corresponding series are` -1+(-1/2)+(-3/2)+(-6)+(-6/5)`
