Select the number from among the given options that can replace the question mark (?) in the following series.
145, 175, 235, 265, 325, ?, 415
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 355.
The logic used here is:
145, 175, 235, 265, 325, ?, 415
145 + 30 = 175
175 + 60 = 235
235 + 30 = 265
265 + 60 = 325
325 + 30 = 355
355 + 60 = 415
Hence, option 4 is the correct answer.
