Question

Determine the sum of the infinite geometric series -1-1/sqrt6-1/6+...

Answer 1

that is a geometric series, S=a+a*q+a*q^2+....
you should first determine the value of q and then you can calculate the summation by a well-known formula

Answer 2

so would it be -1/(1-1/sqrt6) ?

Answer 3

see the q=1/sqrt(6), and as the q<1 we may write:
S=a/(1-q)=-1/(1-1/sqrt(6)). so you are right

Answer 4

Okay! so what exactly would the sum be? i'm still a bit confused

Answer 5

take it easy. you are a sharp student just trust yourself. (your answer is right)

Answer 6

According to my homework site it is not correct unfortunately

Answer 7

repeat it once again but I think that is true
