36...49....64...81...100...121...144
They are the square numbers.
The next number is -21
The sequence appears to consist of numbers formed by concatenating consecutive odd numbers: 1, 4, 9, 16, 25. These numbers are the squares of the first five integers: 1², 2², 3², 4², and 5². The next number in this pattern would be 36, which is 6². Therefore, the next number in the sequence is 36.
