Question 550802
<pre>
The artithmetic series is

$0.01 + $0.02 + $0.03 + ... + $3.63 + $3.64 + $3.65

with d = $0.01

S<sub>n</sub> = {{{n/2}}}(a<sub>1</sub> + a<sub>n</sub>)

S<sub>365</sub> = {{{365/2}}}($0.01 + $3.65)

S<sub>365</sub> = {{{365/2}}}($3.66) = $667.95

[But don't forget that 2012 is a leap year and has 366
days, not 365.  So if that happened in 2012 it would be $671.61. :)]
