Question

Find the sum of the following infinite geometric series, if it exists.
3 + 9 + 27 + 81 +…

Answer 1

We cannot determine the sum of an infinite geometric series.

Answer 2

As we know that the formula is:

\(\Large \color{Black}{\Rightarrow a{1 - r^n \over 1-r} }\)

We just can't raise it to the infinity power!

Answer 3

soo it doesnt exist?

Answer 4

Nope it doesnt

Answer 5

thanxxxx

Answer 7

if and only if the value of r<1 then there is a formulae to find the sum of infine gp series otherwise not and in this problem r>1 so can not find...!!
