COMMENTS

Each number n of the sequence represents a number of minutes. This number can also be expressed in h hours (h as large as possible) and m minutes (m is the remainder; if there is no remainder then let m = "00"). The successor of n in the sequence is the simple juxtaposition of h and m.

FORMULA
|
a(n) = 100*floor(a(n-1)/60) + mod(a(n-1), 60).
|
|
EXAMPLE
|
60 reads "60 minutes"; 60 minutes are 1 hour and 00 minutes, thus 100;
100 then reads "100 minutes"; 100 minutes are 1 hour and 40 minutes, thus 140; etc.
