If you have to guess a number 1-5, and only one of them is correct, there is a 20% chance to guess correctly, I got that so far.
So, the number 1-5 that you have to guess is always random. Is there a way to find some pattern in it?
I mean, If "2" is the random number you need to guess, 4 times in a row, isnt the % chance it will be 2 again actually lower than 20%?
How can you find the number with the highest %chance of being correct if you have a long string of the random numbers 1-5

If the numbers are random, there is by definition no pattern that can be applied to estimate the next number. Even in a truly random string of numbers, there will be repeats of varying lengths.

No!
Probability has no memory. If you flip a FAIR coin 1000 times in a row, and it comes up heads every single time, what is the probability you will get heads on the next flip?
If you got anything but 50%, you need to think hard about where you're going wrong. Past results do NOT influence the next result of a truly random process!

If the selection is truly random then with a large amount of repetition, all numbers will have about the same chance of being chosen.
But of course this is statistics, and statistics say anything.

It will always be 20% at all times given that repetition of any number is allowed.
