Concept:The pattern multiplies the first number by 4 and then subtracts 6 to get the second number.Explanation:For 654:2610, calculate 654×4=2616, then 2616−6=2610.For 466:1858, calculate 466×4=1864, then 1864−6=1858.Let the unknown number be x. The relation for ?:322 is x×4−6=322.Add 6 to both sides: 4x=322+6=328.Divide by 4: x=328÷4=82.Answer:The missing number is 82, which matches option D (82).
