Answer:
= - 3
Step-by-step explanation:
There is a common ratio between consecutive terms of the sequence, that is
r = 9 ÷ - 3 = - 27 ÷ 9 = 81 ÷ - 27 = - 243 ÷ 81 = - 3
The recursive formula is of the form
= r = - 3

Given f(x)=10x+4 and g(x)=3x-8
f(x)+f(x)=(10x+4)+(3x-8)=13x-4
13x-4
Question 49
f(x)=x²-3x and g(x)=4x⁵
f(x)*g(x)=(x²-3x)(4x⁵)=4x⁷-12x⁶
4x⁷-12x⁶
