(viii) – 25, – 23, – 21, – 19, ..... (1 mark)

(viii) – 25, – 23, – 21, – 19, ..... (1 mark)

Sol. t₁ = – 25

t₂ = – 25 + 2= – 23

t₃ = – 23 + 2= – 21

t₄ = – 21 + 2= – 19

t₅ = – 19 + 2= – 17

t₆ = – 17 + 2= – 15

t₇ = – 15 + 2= – 13

t₈ = – 13 + 2= – 11

∴ The next four terms of the sequence are – 17, – 15, – 13 and – 11.
