To solve these kinds of questions you need to know some stuff. You will have 12 _ _ _ _ -13 a = 12 An = -13 n = 6 So we have to find d [Common difference] :D An = a + (n-1)d -13 = 12 + (5)d d = -5 Now I hope you know how to go about this... :D Understood this? :)

  • AkashdeepDeb
You will have 12 _ _ _ _ -13 a = 12 An = -13 n = 6 So we have to find d [Common difference] :D An = a + (n-1)d -13 = 12 + (5)d d = -5 COMMON DIFFERENCE = -5 Second term = a + d = 12 - 5 = 7 Third term = a+2d = 12-10 = 2 Understood this? :)
