There are many sets of numbers with an average of 50.Two numbers with an average of 50 is 49 and 51.
The "average" of a bunch of numbers means (the sum of all the numbers in the bunch) divided by (the number of numbers in the bunch).
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.
The average of the remaining numbers is 38.

Arithmetic:The computing of numerals and numbers.
If you want to calculate the average of a list of numbers, add the numbers together and divide it by the number of numbers.
The average of two numbers.
The average of a group of numbers is(the sum of all the numbers in the group)/(how many numbers there are in the group)
The average, in this case, is the sum divided by 4 (since there are 4 numbers).
