Question

Find the common difference of the A.P. and write the next two terms:
(i) $51,59,67,75,\dots$
(ii) $75,57,59,51,\dots$
(iii) $1.8,2.0,2.2,2.4,\dots$
(iv) $0,\frac{1}{4},\frac{1}{2},\frac{3}{4},\dots$
(v) $119,136,153,170,\dots$

Answer 1

(i) d = 59-51 = 8
Next terms => 83, 91

(ii) It is not an AP because the difference of every two consecutive terms is not constant.

(iii) d= 2.0-1.8=0.2
Next terms => 2.6, 2.8

(iv) d =
Next terms => 1,

(v) d = 136-119 = 17
Next term => 187, 204
