- Homework Statement
- The sum of series ##1+(1/1!)(1/4)+(1.3/2!)(1/4)^2+(1.3.5/3!)(1/4)^3.....## to infinity is

- Relevant Equations
- sum of infinite gp=##a/(1-r)##

Sum of infinite agp=##ab/(1-r)+dbr/(1-r)^2##

I tried by

##S=1+(1/1!)(1/4)+(1.3/2!)(1/4)^2+...##

##S/4=1/4+(1/1!)(1/4)^2+(1.3/2!)(1/4)^3..##

And then subtracting the two equations but i arrived at nothing What shall i do further?

##S=1+(1/1!)(1/4)+(1.3/2!)(1/4)^2+...##

##S/4=1/4+(1/1!)(1/4)^2+(1.3/2!)(1/4)^3..##

And then subtracting the two equations but i arrived at nothing What shall i do further?
