Find the missing number in the following series.
71, 65, 59, (…), 47, 41

Given: 71, 65, 59, (…), 47, 41

Check the difference between consecutive terms.

71 – 65 = 6

65 – 59 = 6

59 − (missing) = 6

Thus, the pattern involves subtracting 6 from each term.

59 – 6 = 53

Verify the pattern.

53 – 6 = 47

47 – 6 = 41

The missing number is 53.
