Count positions from the specified ends of the sequence carefully; the 8th from left is the 8th digit starting from the left, and 1st from right is the very last digit.
Identify 8th digit from the left
Counting from the left in the series '8, 9, 7, 1, 4, 1, 5, 7...', the 8th digit is 7.
Identify 1st digit from the right
Looking at the rightmost end of the series '...3, 1, 7', the 1st digit from the right is 7.
Calculate the sum
The sum of these two digits is 7 + 7 = 14.
A: 17 is incorrect as it is not the sum of 7 and 7. B: 16 is incorrect. D: 11 is incorrect.
C is correct because the 8th digit from the left is 7 and the 1st digit from the right is 7, resulting in a sum of 14.
Always verify the starting position (left vs right) and re-count at least twice to avoid off-by-one errors in series questions.
