Add the previous 2 numbers to get the next number.
i0 = 4; in = in-1 - 3
5-30-6-42-7-56-8-72
8. Each number is the sum of the previous two.
+2, probably.

multiplication pattern
Add 3n-1. For example 1 + 30 = 2 2 + 31 = 5 5 + 32 = 14 14 + 33 = 41
5-30-6-42-7-56-8-72
The pattern is: -8, -7, -5, -2, 2, 7, 13, 20 The series is: +1, +2. +3. +4. +5, +6. +7, etc.
11205 Pattern rule: Start at 1. Multiply by 7, and subtract 2.
8. Each number is the sum of the previous two.
There are actually more than a pattern rule for that type of sequence. The pattern rule is not obvious. The sequence is actually this: an = 5a(n - 2) for n > 2, such that the seed values are a1 = 1 and a2 = 5. Another pattern rule is the number of palindromes using a maximum of five different symbols. The third one is the Inverse Binomial Mean transformation of the Fibonacci sequence.
There is no rule. However, this pattern is known as the Fibonacci sequence, after the Italian mathematician Leonardo of Pisa. Each subsequent number is the sum of its two preceding numbers.
+2, probably.
Start at 1. Multiply by 3. Subtract 1. Multiply by 3. Subtract 1. Repeat this pattern.
