Find the sum, (if it exists), of the infinite geometric sequence with first term 1 and r= -1/4

Answer 1

Sum of infinite series
\[= a{(1-r^n) \over {1-r}}\]

where
a-->first term
r-->common ratio

Answer 2

I meant sum of geometric sequence

Answer 3

so 1*(1-(-1/4)/(1-(1/3)) ?

Answer 4

last term 1/4**

Answer 5

No. Instead of n , you should put infinity

Answer 6

So basically, you get
1*(1-(0)/(1-(1/4))
