With these types of codes, pairs are usually a good starting point

62 72 25 65 35 62 62 04 72 83 13 63 75 35 62 23 03

Let’s try and see where the numbers in the passcode would fall. We have 65 & 35 for prefix and 75, 35 & 62 for suffix. Not much there. Let’s try reversing the string

30 32 26 53 57 36 31 38 27 40 26 26 53 56 52 27 26

Again, let’s look at where numbers should fall. We have 53 & 57 for prefix and 53, 56 & 52 for suffix. Now we have something.

Looks like math. After trying a few number like 100 and 110, 109 gave the answer. You need to subtract the pairs from 109 to get

`79 77 83 56 52 73 78 71 82 69 83 83 56 53 57 82 83`
