The sum of the first seven positive INTEGERS is 28. The sum of the fisrt seven positive numbers is infinitesimally small.
63
the answer is 49.
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.
