SSC CHSL Premium Mock 03 – Q029

Question:

Find the wrong term in the series:
512, 508, 500, 488, 473, 452, 428

श्रृंखला में गलत पद ज्ञात कीजिए:
512, 508, 500, 488, 473, 452, 428

Options:

  • 488
  • 473
  • 452
  • 428
  • 488
  • 473
  • 452
  • 428

Correct Answer: b)

Explanation:

Difference between consecutive terms:
512 – 508 = 4
508 – 500 = 8
500 – 488 = 12
488 – 16 = 472 (given 473)
472 – 20 = 452
452 – 24 = 428
Hence, 473 is the wrong term; it should be 472.

पदों का अंतर देखें:
512 – 508 = 4
508 – 500 = 8
500 – 488 = 12
488 – 16 = 472 (श्रृंखला में 473 दिया गया है)
472 – 20 = 452
452 – 24 = 428
अतः गलत पद 473 है, इसके स्थान पर 472 होना चाहिए।
