Which of the following is most likely the next step in the series?
O A.
B.
O
O D.

C

Explanation: Since it is always going up we can eliminate answered A and D. Then you are between C and B. I would go with C because it goes up significantly more than answer B. B goes up 4 dots while C goes up 8 dots.

Answer d; a supplementary angle = 180°, so if that angle = 150°, y would = 30°.

If you make you answer for clear i can answer it : )
