The series does not converge. Let s(n) be the partial sum of the series. s(1) = 4, s(2) = 1, s(3) = 0, s(4)=4, etc. It is plain to see that s(n) is periodic, i.e. that s(n) = s(n+3). Hence, s(n) does not approach a limit as n -> infinity, so the series does not approach a fixed value. Therefore, it diverges.
It is: 431+478 = 909
0.24 + 431 + 9.4 + 508 = 948.64
-946024
6 + 2 = 12 x 431= 5172
431, as it was.
The positive integer factors of 431 are: 1, 431
432-431 = 1
431 and 1 = 431 + 1 = 432
1 x 431, 431 x 1
12.5% of 431= 12.5% * 431= 0.125 * 431= 53.875
431. 43100/100=431 or 43100/100= 431
