A Correct answer
Explanation

This is an alternating series. The second series (80, 87, 94) increases by 7 each time consistently. The first series should follow a pattern but 740 breaks it. If we examine 648, 740, 760 - the jumps are +92 and +20, which is inconsistent. 740 is likely the wrong number that disrupts the pattern.
