Identify only the required positions first instead of transforming the entire string: the 2nd from the left and 3rd from the right.
Identify only the required positions first instead of transforming the entire string: the 2nd from the left and 3rd from the right.
Analyze the input number
The number is 7 2 6 5 9 3 1 4. There are 8 digits in total.
Identify target digits
The second digit from the left is 2. The third digit from the right (counting from 4, 1, 3) is 3.
Apply operations to target digits
Digit 2 is even, so add 2: 2 + 2 = 4. Digit 3 is odd, so subtract 1: 3 - 1 = 2.
Calculate the sum
The sum of the transformed digits is 4 + 2 = 6.
A: 4 is incorrect because it fails to account for the transformation of the second digit. B: 12 is incorrect as it is a result of miscalculating the arithmetic operations. C: 8 is incorrect as it does not follow the odd/even transformation logic correctly.
D is correct because the second digit from the left (2) becomes 4, and the third digit from the right (3) becomes 2, totaling 6.
When asked for specific positions in a sequence, do not waste time rewriting the entire series; only calculate the digits required by the question.
