चलो `a_n` बनो `n^(t h)` एक एपी अगर की अवधि `sum_(r=1)^(100)a_(2r)=alpha&sum_(r=1)^(100)a_(2r-1)=beta,` तो एपी का आम अंतर है `alpha-beta` (ख) `beta-alpha`  `(alpha-beta)/2` (डी) इनमें से कोई नहीं

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

দিন `a_n` থাকা `n^(t h)` একটি এপি যদি শব্দ `sum_(r=1)^(100)a_(2r)=alpha&sum_(r=1)^(100)a_(2r-1)=beta,` তারপর এপি এর সাধারণ পার্থক্য হল `alpha-beta` (খ) `beta-alpha`  `(alpha-beta)/2` (ঘ) এইগুলির মধ্যে কেউই নয়
