Hi,

I guess this i rather simple task but somehow i cannot get my head arround it. So what i have is a set S of random numbers that are generated in the following way:

get a number (random 1-10)

for 1 to inf

get a number (random 1-10) bigger or equal to the number on a prevoius position minus 1

So the set looks like this:

i : 1 2 3 4 5 6 7 8 9 0 1 2 3 ....

S: 5 4 9 8 7 6 5 4 6 6 6 6 5 ....

what i want to show is that for some integer z in I, if z is smaller then the value on position i then the value on position i minus z <= then the value on position (i plus z).

so

i= 4

value of i = 8

z= 5

i+z= 9

value of 9 = 6

if z< 8 then 8-4 <= 6

Can someone give me a kick in the right direction?

thank you !
