Find the pattern!

Find the pattern behind 12 digits numbers series Samples provided Level: easy-medium Explanations: -We have 12 digits numbers -Last 4 digits define the sum -Add all 12 the numbers together to have a sum of the list defined by the 4 digits -Based on already 1 valid serie of 12 numbers, we can find all the remaining serie We need to find the pattern behind the 4 last digits (so we don't need a valid example to find the remaining series)
