Answer 2

The sixth term will be 20.

Given: The sum of 11 results is 55. the sum of the first 6 results is 30 and that of the last 6 is 45.

To find: We have to find the sixth term.

Solution:

The sum of 11 results is 55.

The sum of the first 6 results is 30 and that of the last 6 is 45.

Let the sixth term be x.

Thus the value of x will be-

x=sum of first six term+ sums of the last six-term- the total sum of the numbers.

x=30+45-55

x=20

Thus the value of x is 20.

So, the sixth term will be 20.
