Question

if the sum of'n'. terms of an AP is s=3n+2n then it's common difference is​

Answer 1

Answer:

Question is incorrect!!

Step-by-step explanation:

There is some fault in your question. The sum of terms of an AP having non-zero common difference is of the form an² + bn

Because Sₙ =

$\frac{n}{2}(2a+(n-1)d)\\\\an + \frac{nd}{2}(n-1)\\\\an + \frac{n^{2}d}{2} - \frac{nd}{2}$

So please post the correct question.

Thanks!
