Identify the missing numbers respectively in the above pattern. ​​

2 × 1 = 2
3 × 2 = 6
5 × 3 = 15
7 × 4 = 28
11 × 5 = 55
13 × 6 = 78
17 × 7 = 119
19 × 8 = 152
__ × 9 = ____
The numbers on the left before the multiplication sign are prime numbers:
2, 3, 5, 7, 11, 13, 17, 19 …
The next prime number after 19 is 23.
So we take 23×9.
That equals 207.
Therefore, the missing numbers are 23 and 207.
