Question 876674: I need help with this word problem.. thank you~
Ted has 6 different fruits and lines them up in this order: banana, coconut, grape, melon, kiwi, and berry. If he continues to put fruits in the same order for an infinite amount of times, what is the 75103rd fruit in this sequence?

Instead of numbering the fruits starting with 1, let's number them
starting with 0, that is:
0 = banana
1 = coconut
2 = grape
3 = melon
4 = kiwi
5 = berry
6 = banana
7 = coconut
8 = grape
9 = melon
10 = kiwi
11 = berry
12 = banana
...
That way each multiple of 6 is banana. So to find
the nth fruit, we only need to divide n by 6 and take
the remainder. If the remainder is 0, the fruit is
banana. If the remainder is 1 then the fruit is coconut,
and so forth up to a remainder of 5 which will give the
fruit berry.
Since we started numbering with 0 instead of 1, the
75103rd fruit will actually be the 75102nd fruit by
our system of numbering.
[That's because since fruit #1 is what we are calling
fruit #0, then fruit #75103 would be what we would be
calling fruit #75102.]
So we divide 75102 by 6
12517
6)75102
6
15
12
31
30
10
6
42
42
0
The remainder is 0, so the answer is 'banana'.
