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.?
So it is obviously 1,5 ,9 and the rule is propably 4 at as time or add four .
the numbers are 1,5,9,...
The nth white bead is bead number
4n-3
1 5 9
Barb is making baby necklace she strings 01 white bead then three blue
Great job 👍👌
To find the numbers for the first eight white beads in Barb's pattern, we need to understand the pattern first.
In the given pattern, Barb strings 1 white bead, then 3 blue beads, then 1 white bead, and so on. This means that after every set of 3 blue beads, there is always 1 white bead.
To identify the numbers for the first eight white beads, we can count the number of sets in the pattern. Each set consists of 3 blue beads followed by 1 white bead.
Let's break it down step by step:
1. Start with the first white bead.
2. Count the sets: 1st set, 2nd set, 3rd set, and so on.
3. Multiply the number of sets by the size of each set (which is 4 beads in total — 3 blue + 1 white).
4. For each white bead, add 1 to the sequence.
Now, let's write down the numbers for the first eight white beads:
1st white bead: 1 (1 set * 4 beads + 1 = 1)
2nd white bead: 5 (2 sets * 4 beads + 1 = 5)
3rd white bead: 9 (3 sets * 4 beads + 1 = 9)
4th white bead: 13 (4 sets * 4 beads + 1 = 13)
5th white bead: 17 (5 sets * 4 beads + 1 = 17)
6th white bead: 21 (6 sets * 4 beads + 1 = 21)
7th white bead: 25 (7 sets * 4 beads + 1 = 25)
8th white bead: 29 (8 sets * 4 beads + 1 = 29)
Therefore, the numbers for the first eight white beads in Barb's pattern are 1, 5, 9, 13, 17, 21, 25, and 29.
The rule for the pattern is to add a set of 3 blue beads followed by 1 white bead after each previous set.
