Question

If the average number of 8 terms is given to be 40 and the average of first 6 terms is given to be 35.What is the average of the remaining 2 terms?

Answer 1

Sum of all the $8$ terms $=320.$
The sum of first $6$ terms $=210$
Now , the sum of remaining terms $=320-210=110$
So , the average of $2$ terms would be $=110/2=55$
