  • $\begingroup$ Are the four sequences related? If not, there are too many possible answers, see OEIS $\endgroup$

Answers are

5, 5, 4, 8

Explanation, those series go 2 by 2:

Sequences are made by separing odd position digits and even position digits of e and pi

Sequence 3 with sequence 1

One digit out of 2 of number e: 2,71828... Third sequence starts with integer part 2

Sequence 2 with sequence 4

One digit out of 2 of number pi: 3,14159... Second sequence starts with integer part 3
