Write the first five terms of the sequence in the corresponding series.
`a_1=-1, a_n=a_(n-1)/n, n ge 2`

Text Solution

Verified by Experts

Given `a_1=-1`
`a_2=a_1/2=-1/2, a_3=a_2/3=-1/2/3=-1/6, a_4=a_3/4=-1/6/.4=-1/24, a_s=a_4/5=-1/24/5=-1/120`
The required,series is `-1, -1/2, -1/6, -i/24, -1/120, . . .`
