In following number series, two terms have been put within brackets. Choose the appropriate option - Look at this series: 201, 202, 204, 207, . . .What number should come next?
Answer: D. 211
In this addition series, 1 is added to the first number (201 + 1 = 202); 2 is added to the second number (202 + 2 = 204); 3 is added to the third number (204 + 3 = 207); and 4 is added to the third number. (207 + 4 = 211) So the answer is d = 211.
