If the numbers in the sequence are hexadecimal, then they are based on 16 instead of 10. This means that each digit can represent 16 different values, from 0 to 15. The values from 10 to 15 are written as A, B, C, D, E and F123.

To change the answer, you would need to convert the hexadecimal numbers to decimal numbers first, and then apply the same formula as before. To convert a hexadecimal number to a decimal number, you multiply each digit by 16 raised to the power of its position from right to left, and then add them up24.

For example, if the sequence is A9, B2, BB, C4, CD, then you would convert each term to decimal as follows:

A9 = (10 × 16^1) + (9 × 16^0) = 160 + 9 = 169
B2 = (11 × 16^1) + (2 × 16^0) = 176 + 2 = 178
BB = (11 × 16^1) + (11 × 16^0) = 176 + 11 = 187
C4 = (12 × 16^1) + (4 × 16^0) = 192 + 4 = 196
CD = (12 × 16^1) + (13 × 16^0) = 192 + 13 = 205
Then you would apply the formula to find the next term in decimal:

an = an-1 + n
a6 = a5 + 6
a6 = 205 + 6
a6 = 211
Finally, you would convert the decimal number back to hexadecimal by dividing it by 16 repeatedly and writing the remainders in reverse order24.

211 ÷ 16 = 13 remainder 3
13 ÷ 16 = 0 remainder D
So the next term in hexadecimal is D3.
