Find the common difference and write the next four terms of each of the following arithmetic progressions:

(i)

(ii)

(iii)

(iv)

(i)

Common difference, d = -2 – 1 = -3

A₅= -8 – 3 = -11

A₆= -11 – 3 = -14

A₇= -14 – 3 = -17

A₈= -17 – 3 = -20

(ii)

Common difference, d = -3 – 0 = -3

A₅= -9 – 3 = -12

A₆= -12 – 3 = -15

A₇= -15 – 3 = -18

A₈= -18 – 3 = -21

(iii)

Common difference, d = + 1 =

A₄= + =

A₅= + = = 4

A₆= 4 + =

A₇= + = =

(iv)

Common difference, d = + 1 =

A₄= + =

A₅= + =

A₆= + =

A₇= + = 0
