#1.
The kth odd number is 2k-1
Think about it : 1,3,5,...
#2
It will be a multiple of 60. So, what's the biggest 3-digit multiple of 60?
#3
There are 203 numbers from 101-303.
Knock off one end, since both are odd, and half of the remaining 202 are even.
#4
same thing
#5
52/8 = 6 remainder 4.
So, the 4 extra cards go to 4 of the players, giving them 7 cards each. So, how many don't get the extra card?

1, 3 , 5 , 7 , 9 .......
first is 1 = 2 - 1
second is 3 = 4 - 1
third is 5 = 6 - 1
number (n) = 2 n - 1
number (117) = 2(117) - 1
first is 1 = 2 - 1
second is 3 = 4 - 1
third is 5 = 6 - 1
number (n) = 2 n - 1
number (117) = 2(117) - 1
