A) 16	B) 32	C) 33	D) 54	E) 64
You can just write out the pattern and count: RGWBYRGWBYRGWBY... But to save time a good test taker will just look for a pattern. Min # is 3, because W is the third one. Then every 5 beads another white comes, so it must be 3+5=

<output>23</output>
23   So you see it ends in either 8 or 3. Pick an answer that ends in either 8 or 3. Only one answer does, 33.
