looks like we are taking the perfect squares and alternating them - and +
A perfect square is any rational number that is the square of another rational number.
1 ^ 2 = 1
2 ^ 2 = 4
5 ^ 2 = 25
6 ^ 2 = 36
7 ^ 2 = 49
etc.
Your series is a perfect square with negative odd numbers.
The next 3 numbers are :
- 25 , 36 , - 49
1 ^ 2 = 1
2 ^ 2 = 4
5 ^ 2 = 25
6 ^ 2 = 36
7 ^ 2 = 49
etc.
