Select the number from among the given options that can replace the question mark (?) in the following series.
213, 216, 225, 240, 261,?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 288.
Given series: 213, 216, 225, 240, 261,?
The series follows this pattern:
213 + 3 = 216
216 + (3 + 6) = 216 + 9 = 225
225 + (9 + 6) = 225 + 15 = 240
240 + (15 + 6) = 240 + 21 = 261
261 + (21 + 6) = 261 + 27 = 288
So, the next term in the series is 288.
