The second and third rectangular numbers are 6 and 12
8924 is the number that comes 1100 numbers after 7824.
The prime numbers and the squares of primes between 2 and 20: 3, 4, 5, 7, 9, 11, 13, 17 and 19.
Rectangular numbers are a subset of composite numbers. The squares of prime numbers will be composite but not rectangular.

26,200 - 1,100 = 25,100
20 and 30 are rectangular numbers (4 * 5 and 5 * 6). There are none in between them.

1111 is the only one.

4, 6, 8, 9, 19
Since all the numbers in that range start with "11", there is really only one option!
The second and third rectangular numbers are 6 and 12
