Insert the missing term:

The correct answer is Option (2) → 57

The rule is found from the first circle and then applied to the second: the number in the middle is the product of the two upper numbers minus the product of the two lower numbers.

• First circle: \(9\times8-6\times4=72-24=48\)

• Second circle: \(12\times10-7\times9=120-63=57\)
