It takes exactly 74 colored beads on a string to make a necklace. The beads are strung in the following order: one red, one orange, two yellow, one green, and one blue. Then the pattern repeats starting again with one red bead. If the first bead of the necklace is red, what is the color of the last bead used to make the necklace?

is it yellow??

Hi!

Well, if the pattern goes in that order, and there are 74 beads, then we can first see how many times we can repeat that pattern in the necklace.

74/6=12.3333333333333(repeating)

So we can do that pattern 12 times.

12x6=72

After we do that pattern 12 times, we have 2 beads left over, so the first two beads of the pattern will be placed. The second bead should be orange. (First bead red, second bead orange).

Hope this helps!
