n

' odd number of terms and

S_2

, the sum of the terms of the series in odd places, then

View answer and explanation

Correct option: A

\frac{2 n}{n+1}

Option A (

\frac{2 n}{n+1}

) is correct because the ratio of the sum of an arithmetic series with 'n' odd number of terms to the sum of the terms in odd places is 2n/(n+1).
