The average of the first 20 multiples of 7 can be represented by the following equation: Average = (7 * (1 + 2 + 3 + ... + 20)) / 20 = (7 * (20 * 21)) / (20 * 2) = 1472 / 40 = 73.5
This equation first calculates the sum of the first 20 multiples of 7 by multiplying 7 by the sum of the first 20 natural numbers.
The sum is then divided by the total number of numbers to obtain the average, which is 73.5
Output: The second number is the product of digits of first number. Then 1 × 6 = 6 .
