Barb is making a bead necklace. She strings 1 white bead, then 3 blue beads, then 1 white bead, and so on.Write the numbers for the first eight beads that are white.What is the rule for the pattern

the pattern is that. I don't know what write the numbers means..

To find the rule for the pattern, let's first look at the sequence of beads:
1 white, 3 blue, 1 white, 3 blue, 1 white, ...
We can see that the pattern repeats: 1 white, 3 blue. So, let's break it down further:
1st bead: white
2nd bead: blue (part of the 3 blue sequence)
3rd bead: blue (part of the 3 blue sequence)
4th bead: blue (part of the 3 blue sequence)
5th bead: white
6th bead: blue (part of the 3 blue sequence)
7th bead: white
8th bead: blue (part of the 3 blue sequence)
From this analysis, we can observe that the white beads occur in a regular pattern: 1 white, followed by a sequence of 3 blue beads. This pattern then repeats.
To find the numbers for the first eight beads that are white, we can follow this pattern:
1st white bead: 1
2nd white bead: 5
3rd white bead: 7
4th white bead: 11
5th white bead: 13
6th white bead: 17
7th white bead: 19
8th white bead: 23
So, the numbers for the first eight white beads in the pattern are: 1, 5, 7, 11, 13, 17, 19, 23.
Therefore, the rule for the pattern is that the white beads occur at the positions of prime numbers in the sequence.
