Directions (75-79): Read the given number series carefully to answer the related questions:

692    318    196     486 7   54

What is the sum of the 2nd highest number and 2nd lowest number?

The correct answer is 1010.

Step-by-step Explanation:

Step 1: Identify the numbers in the given series
Based on the provided series, the five three-digit numbers are:
692, 318, 196, 486, and 754.

Step 2: Arrange the numbers in ascending order to identify the required values
Arranging the numbers from lowest to highest, we get:
196 < 318 < 486 < 692 < 754

From this ordered list, we can identify:
- The lowest number is 196, so the 2nd lowest number is 318.
- The highest number is 754, so the 2nd highest number is 692.

Step 3: Calculate the sum of the 2nd highest and 2nd lowest numbers
Now, we add these two values together:

$\mathrm{Sum}=692+318$

$\mathrm{Sum}=1010$

Thus, the sum of the 2nd highest number and 2nd lowest number is 1010.
