Determine the first four terms of the sequence defined by, `u_(1) = -3, u_(n) = (1)/(n-1). u_(n-1) ` for `n ge 2`. Also find the series of first five terms of the sequence.

Text Solution

Verified by Experts

The correct Answer is:
the first four term of the sequence are : (-3), (-3), `(-(3)/(2)), -(1)/(2)` and the series of first five terms of the sequence is `u_(1) + u_(2) + u_(3) + u_(4) + u_(5) = (-3) + (-3) + (-(3)/(2)) + (-(1)/(2)) + (-(1)/(8))`.
