Determine whether the sequence converges or diverges. If it converges, give the limit.

108, -54, 27, negative 27 divided by 2, ...
Can someone help with this?

Respuesta :

As you keep multiplying by -1/2, the absolute value of the next number in the sequence decreases.  As a result, the sequence converges, with limit 0 (as the lowest value in the range of absolute value is 0).
