Check whether - 150 e is a term of AP 11,8,5,2....... |
|
Answer» no Let - 150 is the nth of AP 11,8,5,2.......which means that an=-150Here, first term =a=11,d=8-11=-3Using formula an=a+(n-1)d, to find nth term of AP-150 =11+(n-1)(-3) =-150=11-3n+3=3n=164=n=164/3But, n cannot be in fractions Therefore, our supposition is wrong, - 150 cannot be term in AP |
