Set S = 1
Set P = 1
Set previous answer = 1

answer = S * P + previous answer + R
R = 26

After this => S + 1 and P + 1 ('answer' becomes 'previous answer') + 26
then repeat this till you have S = 41294.

The final key will be the value of 'answer' when S = 41294.

Example:
So if R = 15..

17 = 1 * 1 + 1 + 15
36 = 2 * 2 + 17 + 15
60 = 3 * 3 + 36 + 15

Submit the correct answer and you will recieve a flag. Have fun ;D
