The numbers for the first eight beads that are white are; 1, 5, 9, 13, 17, 21, 25, 29
<h3>Arithmetic Sequence</h3>
We are told that she strings in this order;
- 1 white
- 3 blue
- 1 white bead
Now, after the first white bead, the next white bead is the 5th bead in total.
This means the difference in interval between white beads is; 5 - 1 = 4 beads
Thus, the numbers for the first eight beads that are white are;
1, (1 + 4), (1 + 4 + 4), (1 + 4 + 4 + 4).....
Thus, we have;
1, 5, 9, 13, 17, 21, 25, 29
