Find the wrong number among the given series. निम्न श्रृंखला में गलत संख्या ज्ञात कीजिए। 1956, 1968, 1976, 1982, 1988, 1992

The series should be prime numbers ending with even numbers or following a specific pattern. Looking at the differences: 1968 - 1956 = 12, 1976 - 1968 = 8, 1982 - 1976 = 6, 1988 - 1982 = 6, 1992 - 1988 = 4. The pattern 12, 8, 6, 6, 4 doesn't show clear progression. However, if we consider that these are leap years: 1956 (leap), 1968 (leap), 1976 (leap), 1982 (not leap), 1988 (leap), 1992 (leap). The year 1982 is not a leap year (not divisible by 4), while all others are leap years. Hence 1982 is the wrong number.
