Answer:
-7 is the pattern in the sequence. In other words, we subtract 7 from the numbers.
Step-by-step explanation:
31 - 7= 24
24 - 7= 17
17 - 7= 10
We subtract 7 from 31 to get 24. We subtract 7 from 24 to get 17. We subtract 7 from 17 to get 10.
That is 100 choices for the first number
99 for the 2nd number
98 for the 3rd number
in total, there are 100*99*98 or 970200 possible combos of winning numbers

If you're looking for x it is 5 which also makes YZ equal 5
