Thank you Tayzar
You are welcome
Answer should be 38 white beads instead of 40.
Note that the 1st and last bead are black. There are 19 repeating groups of black+white+white, followed by 1 single black at the end.
19 x 2 = 38 white beads.

Yeah. My teacher also said that 40 is a wrong answer. Thanks
