Concept:The pattern is that the difference between the first number and the second number is the same in both pairs.Explanation:We check each option using the relation $X - 16.2 = 23 - Y$.Option A: $X=19$, $Y=22.2$$19 - 16.2 = 2.8$ and $23 - 22.2 = 0.8$Since $2.8 \neq 0.8$, this option is incorrect.Option B: $X=17$, $Y=22.2$$17 - 16.2 = 0.8$ and $23 - 22.2 = 0.8$Since $0.8 = 0.8$, this option follows the same pattern.Option C: $X=19$, $Y=21.2$$19 - 16.2 = 2.8$ and $23 - 21.2 = 1.8$Since $2.8 \neq 1.8$, this option is incorrect.Option D: $X=17$, $Y=21.2$$17 - 16.2 = 0.8$ and $23 - 21.2 = 1.8$Since $0.8 \neq 1.8$, this option is incorrect.Answer:$X = 17$ and $Y = 22.2$, which is Option B.
