Universe Sequence

What do these numbers mean??

1-2-4-8-7-5-1-2-4-8-7-5-1-2-4-8-7-5 || 3-6-3-6-3-6 || 9-9-9-9-9-9-9-9

formulas: a=b, c=a+b || ((a+b)-10)+1 || Rule: if(a+b)>=10 then c=((a+b)-10)+1 else c=a+b

Using the formula:
a=b with a = 1 therefore c = 1 + 1 = 2
a=b with a = 2 therefore c = 2 + 2 = 4
a=b with a = 4 therefore c = 4 + 4 = 8
a=b with a = 8 therefore c = 8 + 8 = 16 Rule applies: c = (16-10) + 1 = 6 + 1 = 7
a=b with a = 7 therefore c = 7 + 7 = 14 Rule applies: c = (14-10) + 1 = 4 + 1 = 5
a=b with a = 5 therefore c = 5 + 5 = 10 Rule applies: c = (10-10) + 1 = 0 + 1 = 1

** This sequence with repeat forever..... **

Sequence: 1-2-4-8-7-5

Using the formula:
a=b with a = 3 therefore c = 3 + 3 = 6
a=b with a = 6 therefore c = 6 + 6 = 12 Rule applies: c = (12-10) + 1 = 2 + 1 = 3

** This sequence with repeat forever..... **

Sequence: 3-6

Using the formula:
a=b with a = 9 therefore c = 9 + 9 = 18 Rule applies: c = (18-10) + 1 = 8 + 1 = 9

** This sequence with repeat forever..... **

Sequence: 9

Asking DALL-E 3 with simple prompt:

1-2-4-8-7-5-1-2-4-8-7-5-1-2-4-8-7-5 || 3-6-3-6-3-6 || 9-9-9-9-9-9-9-9

** No words, just 3 number sequences
