Question

The denominator of the seventh term is
125
216
343
512

Answer 1

343 will be your answer

Answer 2

Answer: Thus, Third option is correct.

Explanation:

Since we have given that

`1,(1)/(8),(1)/(27),(1)/(64),...............(1)/(n^3)`

So, we can see the pattern:

General term of the series is given as

`(1)/(n^3)`

So, we just put the value of n = 7, to get the required denominator:

`(1)/(7^3)=(1)/(343)`

Hence, the denominator of the seventh term is 343.

Thus, Third option is correct.
