Answer 1

(a + l) * n/2

where a = 1st no., l = last no, n = number of nos.
[and if n is not immediately available, n = l - a + 1]

(.01 + 3.65) * 365 / 2

$3.66* 365 /2 =

667.95

Answer 2

$452.00 You begin with 365 then add all the way down until you reach 1. 365+364= 729+363= 1092.. and so on... the u divide your total by 100...
