To find the average of the first 19 natural numbers, we can add them all up and divide by 19. To add them all up, we can use a formula called the formula to calculate the sum of a sequence. For the first 19 numbers, we can calculate this sum by going over all the numbers from 1 to 19 and adding them one by one. We can express this sequence mathemat ically as the sum from i equals 1 to 19 of i.

The average of the first 19 natural numbers is therefore (1 + 2 +... + 19) / 19.

The answer is C: 10

To find the average (or mean) of the first 19 natural numbers, we need to add up all the numbers from 1 to 19 and then divide by the total count (19 in this case).

The sum of the first 19 natural numbers can be calculated using the formula:

(1 + 2 + 3 + ... + 19) = 19(19/2)

This formula is derived from the arithmetic series formula, where the first term is 1, the common difference is 1, and the number of terms is 19.

Substituting this into the formula for finding the average, we get:

Average = (1 + 2 + 3 + ... + 19) / 19
Average = 19(19/2) / 19
Average = (19^2) / 2

Simplifying, we get:

Average = 192 / 2 = 96

Since we're looking for the option among the given choices, the correct answer is (C) 10, which is the nearest integer to the calculated average of 96/2 = 48. However, option (C) is not equal to the exact average, so it's not the best choice.

Therefore, the correct answer is not among the given options.
