Answer» Correct Answer - B The given numbers are `-10, -6, -2, 2, ….` Here `a_(1)=-10, a_(2)= -6, a_(3)= -2` and `a_(4)=2, ….` Since, `a_(2) - a_(1)= -6-(-10) = -6 +10=4` `a_(3) - a_(2) = -2-(-6)= -2+6=4` `a_(4) - a_(3)=2-(-2)=2+2=4` … … … … … … … … ... ... ... ... ... ... ... ... ... ... Each successive term of given list has same difference i.e., 4. So, the given list forms an AP with common difference, d = 4. |
