To solve the problem, we need to identify the relationship between the pairs of numbers. For the pair 19: 12, the relationship is as follows: (12×2)−5=19 To find the number related to 23 using the same pattern, we set up the equation: (x×2)−5=23 Solving for x : Add 5 to both sides: 2x=23+5=28 Divide by 2: x=‌
