Correct option is B
The given series is:
872, 870, 866, 860, 852, ?
Logic: The differences are decreasing by even numbers in a sequence: −2, −4, −6, −8
872 → 870 (−2)
870 → 866 (−4)
866 → 860 (−6)
860 → 852 (−8)
Following this pattern, the next difference should be −10.
Now calculate the next term:
852 − 10 = 842
Correct Answer: (B) 842
