Thank you for using the timer!
We noticed you are actually not timing your practice. Click the START button first next time you use the timer.
There are many benefits to timing your practice, including:
1) The average of the first 9 integers is 7 2) The average of the last 9 integers is 9
1) since the numbers are consequtive, the average of 9 numbers would be the same as the median. Therefore the 5th number in the sequence is 7
The sequence would be 3,4,5,6,7,8,9,10,11 .. the next two numbers would obviously be 12 and 13
2) since the numbers are consequtive, the average of 9 numbers would be the same as the median. Therefore the 7th number in the sequence is 9 The sequence would be 5,6,7,8,9,10,11,12,13 .. the next two numbers would obviously be 3 and 4
