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

Sufficient

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
