Correct Answer & Explanation
Option D
• In all terms except 564, the first (hundreds) and third (units) digits are identical:
In 232: hundreds digit = 2, units digit = 2
In 343: hundreds digit = 3, units digit = 3
In 454: hundreds digit = 4, units digit = 4
In 676: hundreds digit = 6, units digit = 6
• For 564, the hundreds digit is 5 and the units digit is 4 (which should be 565).
• Hence, 564 is the wrong number.
