Identify the 12th digit by counting from the left and the 2nd digit by counting from the right, then perform the simple addition.
Identify the 12th digit from the left
Counting from the left (6, 3, 0, 4, 7, 5, 5, 6, 8, 3, 6, 6...), the 12th digit is 6.
Identify the 2nd digit from the right
Counting from the right (...3, 0, 6), the last digit is 6, and the 2nd digit is 0.
Calculate the sum
Summing the two identified digits: 6 + 0 = 6.
A: Incorrect (0 + 6 is not 5), B: Incorrect (0 + 6 is not 4), D: Incorrect (0 + 6 is not 7).
C is correct because the 12th digit from the left is 6 and the 2nd digit from the right is 0, making the sum 6 + 0 = 6.
Always map the sequence positions carefully to avoid off-by-one errors; using a pencil to tick off every 5th digit helps.
