Determine whether the following sequence converges or diverges and describe whether it does do so monotonically or by oscillatio

earnstyle [38]

Answer:

D. The sequence diverges by oscillation.

Step-by-step explanation:

an = (-1.00000004)n

From root test

L = Lim n->infinity (|an|)(1/n)

==> L = Lim n->infinity (|-1.00000004n|)(1/n)

==> L = Lim n->infinity (|-1.00000004|n)(1/n)

==> L = Lim n->infinity |-1.00000004|

==> L = 1.00000004 > 1

Hence series diverges.
