- take 0.23 = A
now question is: a+(a/10)+(a/100).......
a[1+(1/10)+(1/100).....]
a[1/(1-(1/10))] {infinite A.P= a/(1-r)}
a*(10/9)
0.23*10/9

- Take out 0.23 from the sequence then,
0.23(1+0.1+0.01+0.001+....)
as its infinite GP [ Sn=a/(1-r)] where a=first term; r=next term/previous term
thus a=1 and r=0.1
sum=0.23*1/(1-0.1)=0.2525 - 7 years agoHelpfull: Yes(0) No(0)
- 0.23+0.023=0.253
0.253+0.002323=0.2553
0.2553+0.0002323=0.25553
0.25553+0.00002323=0.255553
so the answer is 0.2555555555555555 - 5 years agoHelpfull: Yes(0) No(0)
