This is a challenge to test your basic programming skills.
Pseudo code:
Set X = 1
Set Y = 1
Set previous answer = 1
answer = X * Y + previous answer + 3
After that => X + 1 and Y + 1 ('answer' becomes 'previous answer') and repeat this till you have X = 525.
The final answer is the value of 'answer' when X = 525. Fill it in below.
Example:
5 = 1 * 1 + 1 + 3
12 = 2 * 2 + 5 + 3
24 = 3 * 3 + 12 + 3
........................
........................
```
Here a simple python code do the trick
```python
prev = 1
for XY in range(1,526):
curr = XY*XY + prev + 3
prev = curr
print('brixelCTF{'+str(curr)+'}')
```
Response :
```
brixelCTF{48373851}
```
flag : `brixelCTF{48373851}`
