Let `a_n` be the `n^(t h)` term of an A.P. If `sum_(r=1)^(100)a_(2r)=alpha&sum_(r=1)^(100)a_(2r-1)=beta,` then the common difference of the A.P. is `alpha-beta` (b) `beta-alpha` `(alpha-beta)/2` (d) None of these

A

`(alpha-beta)/(200)`

B

`alpha-beta`

C

`(alpha-beta)/(100)`

D

`beta-alpha`

To solve the problem, we need to analyze the given information about the arithmetic progression (A.P.) and the sums of its terms. 1. **Understanding the terms of the A.P.**: Let the first term of the A.P. be \( a \) and the common difference be \( d \). The \( n^{th} \) term of the A.P. can be expressed as: \[ a_n = a + (n-1)d \] ...
