A) \[-5\sqrt{2}\]
B) \[5\sqrt{2}\]
C) \[10\sqrt{2}\]
D) \[-10\sqrt{2}\]
Correct Answer: A
Solution :
Obviously the given series \[2\sqrt{2}+\sqrt{2}+0+.......\] is an A.P. Here\[a=2\sqrt{2},\ d=-\sqrt{2}\]. Hence term of the series \[=2\sqrt{2}+(8-1)(-\sqrt{2})=-5\sqrt{2}\].You need to login to perform this action.
