Lina's Necklace

Lina's making a bead necklace. She is using blue beads and pink beads. She starts with blue. She changes the colour every 10 beads. So far she has 16 beads on her necklace. Suppose Lina adds 10 more beads. How many of each colour will she add? What colour will the 88 bead be? How many of each colour will she have?
