If 227and π appear as two distinct terms of an A.P., then common difference of the A.P. must be

Let the A.P. be a1, a2, ... suppose     am=227 and an=πIf d is the common difference of the A.P., then(m−n)d=am−an=227−π                                 ⇒d=1m−n227−πwhich is a irrational number as π is an irrational number.
