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?
1, 4, 7, 10, ....
nope, I erred.
1, 5, 9, 13 each 4th bead is white.
Help idk the awnswer
To find the numbers for the first eight beads that are white, let's analyze the pattern:
We can see that the pattern begins with 1 white bead, followed by 3 blue beads, then another white bead. The number of blue beads increases by 2 each time.
To find the numbers for the first eight white beads, we can think of this pattern as a sequence. Let's break it down:
1st white bead: 1
2nd white bead: 4 (1 white bead + 3 blue beads)
3rd white bead: 7 (1 white bead + 3 blue beads + 3 blue beads)
4th white bead: 10 (1 white bead + 3 blue beads + 3 blue beads + 3 blue beads)
5th white bead: 13 (1 white bead + 3 blue beads + 3 blue beads + 3 blue beads + 3 blue beads)
6th white bead: 16 (1 white bead + 3 blue beads + 3 blue beads + 3 blue beads + 3 blue beads + 3 blue beads)
7th white bead: 19 (1 white bead + 3 blue beads + 3 blue beads + 3 blue beads + 3 blue beads + 3 blue beads + 3 blue beads)
8th white bead: 22 (1 white bead + 3 blue beads + 3 blue beads + 3 blue beads + 3 blue beads + 3 blue beads + 3 blue beads + 3 blue beads)
So, the numbers for the first eight beads that are white are 1, 4, 7, 10, 13, 16, 19, and 22.
The rule for this pattern can be expressed as follows:
The nth white bead in the sequence can be calculated using the formula: (3n - 2)
Therefore, to find the nth white bead, we multiply n by 3 and subtract 2.
