I snap my fingers once. I wait one second and snap them again. I wait two seconds and snap them a third time. I wait four seconds and snap them again. I wait 8 seconds and snap them again. If this pattern continues, how many times will I snap my fingers in a year?
1+2+4+...2^n up to a year in seconds.
That looks like the sum of a geometric series, where r=2
Use that formula, you know the sum is 1*365*24*3600...find the number of terms.
it looks like you could just solve for
oh and at 1 for the series begining at 1 not zero. appoximately 26 times.
