Question

Determine whether the sequence converges or diverges 108, -18, 3, -1/2

Answer 1

do you know how to determine a geometric series?

Answer 2

yeah

Answer 3

So what is you value of "a" where a is the first term and your "r" and r is the common ratio?

Answer 4

the sequence is being divide by -6

Answer 5

@MathsStar

Answer 6

no: i want you know to find r' . say it out and what your "a" please

Answer 7

are you there?

Answer 8

when the value of "r" you got is greater than or equal to negative one and or less than one or equal to one you should know that The infinite geometric series with -1≤ r ≤ 1 converges to a /(1 - r)
