Question

Find the common difference and write the next four terms of each of the following arithmetic progressions:
(i) $1,-2,-5,-8,\dots$
(ii) $0,-3,-6,-9,\dots$
(iii) $-1,\frac{1}{4},\frac{3}{2},\dots$
(iv) $-1,-\frac{5}{6},-\frac{2}{3},\dots$

Answer 1

(i) d = -2 -1 = -3
Next four terms,
=> -11,-14,-17,-20

(ii) d = -3
Next four terms,
=> -12, -15, -18, -21

(iii) d =

Next four terms,
=>

(iv) d =

Next four terms,
=>
