the number n has to be a multiple of 4 since it iscomplete the pattern
the first red the last white
so we can cancel c and d
and may be A since the number of patterm could be to small for the necklace

does anyone has a clue to deal with that one thanks
(A) 16
(B) 32
(C) 41
(D) 54
(E) 68

The necklace pattern is R G W B Y (R = red, g = green etc.)

So, we have R G W B Y R G W B Y ..... R G W (I may be wrong here since this is what I assume the question meant )

So, we are increasing the beads by 5 until we get to the R G W sequence.

So, 5x + 3 = N.

We will get an integer value for x only if N = 68.

So, I am going with E.
