In the first pattern, all the denominators are squared.
1 squared is 1
2 squared is 4
3 squared is 9
4 squared is 16
5 squared is 25
and the 1 just stays the same.
I'm not sure about the second pattern, because I don't know of an Alexander in office. Maybe it isn't about the presidents...
Abe has 3 letters, and Thomas has 6, and that equals the amount in Alexander, but other than that I'm not sure.

first: 1/1^2 , 1/2^2 , 1/3^2 , 1/4^2 , 1/5^2 ...(^2 means squared)
second: George = $1 (Washington)
Thomas = $2 (Jefferson)
Abe = $5 (Lincoln)
Alexander = $10 (Hamilton)

First one is 1 / N^2
so the next two are 1 / 6^2 = 1/36 ..... and 1 / 7^2 so 1/49
Not American so don't know about the last one.
