Q3. Here are the first four terms of a sequence: 11, 22, 44, 88... a) Write down one expression in terms of n for the nth term of the sequence.

a(n) = 11*2^(n-1)

a1 = 11

a2 = 22 = 11.2

a3 = 44 = 11.2²

a4 = 88 = 11.2³

......

=> this is a geometic with a1 = 11

                                           r = 2

=>

answer: -10

step-by-step explanation:

s(t) = 1 - 10t

s(x) = 1 - 10x

s(x + h) = 1 - 10(x + h)

            = 1 - 10x - 10h

s(x + h) - s(x) = 1 - 10x - 10h - (1 - 10x)

                      = 1 - 10x - 10h - 1 + 10x

                      = -10h

= -10
