Finding the relationship in a list to make an equation.

So I have an equation to form a list of 100 numbers

number[#]=(#*13)%100;
right!!
it looks like this…
1)13
2)26
3)39
4)52
5)65
6)78
7)91
8)4
9)17
10)30
11)43
12)56
13)69
14)82
15)95
16)8

So I need another equation that would give me these numbers
1)77
2)54
3)31
4)8
5)85
6)62
7)39
8)16
9)93
10)70
11)47
12)24
13)1
14)78
15)55
16)32

How would I go about getting an equation for the second list of numbers?

Thanks!

100 - #*23 % 100
Though are you sure it’s more beneficial using a lookup table rather than performing the calculation when required?
