Find the common difference of the A.P. and write the next two terms:

(i)


(ii)


(iii)


(iv)


(v)

(i)


Common difference, d = 59 – 51 = 8


A5 = 75 + 8 = 83


A6 = 83 + 8 = 91


(ii)


Common difference, d = 67 – 75 = -8


A5= 51 - 8 = 43


A6= 43 – 8 = 35


(iii)


Common difference, d = 2.0 – 1.8 = 0.2


A5= 2.4 + 0.2 = 2.6


A6= 2.6 + 0.2 = 2.8


(iv)


Common difference, d = – 0 =


A5= + = 4


A6= 4 + =


(v)


Common difference, d = 136 – 119 = 17


A5= 170 + 17 = 187


A6= 187 + 17 = 204
