a[n]=a[n-1]+3*a[n-1]*(1.0^-10)

how to generate the answer if a[0]=(1.0^-10)

ive done but wen i compared the answer using calculator..the answer is wierd..they r not same..
i used "for" repetition..

thank you

If I solve this homogenous expression I get:

a[n] = (1+3*1^-10)^n*a[0]

Does this help a bit?

kind regards,

instead of putting 1*10^-10, we should write 1.0e-10 in c++...
