63
the answer is 49.
The sum of the first 50 whole numbers is 1,225.
The sum of the first 1,000 whole numbers is 499,500.
The sum of the first 40 whole numbers is 780.
To find the average of all seven numbers, we can use the formula for the average: (sum of all numbers) / (total number of numbers). Given that the average of the first four numbers is 15, the sum of the first four numbers is 15 * 4 = 60. Similarly, the sum of the last three numbers is 8 * 3 = 24. Therefore, the sum of all seven numbers is 60 + 24 = 84. Finally, the average of all seven numbers is 84 / 7 = 12.
