Quizplus · Accepted Answer

The pattern in the equations involves increasing the first number in the multiplication by 2 and the second by 2, then increasing the first number in the subtraction by 2 and the subtracted number by 4. Thus, 6 × 8 = 48 and 7 × 9 = 63. Subtracting 15 from 63 gives 48, which matches the left side of the equation, making option A correct.
