Use function notation to write a recursive formula to represent the sequence: 3, 6,
f(n) = f(n − 1) + 3
f(n) = f(n - 1) + 2
f(n) = f(n-1).3
f(n) = f(n-1)2

f(n)=f(n-1)×2

Step-by-step explanation:

The previous term is being multiplied by 2 to get a term.

First term is 3.

Second term is 3×2=6.

Third term is 6×2=12.

nth term is f(n-1)×2.

Note: f(n-1) is just the term before f(n).

f(n)=f(n-1)×2 with f(1)=3 is the recursive form for this sequence.

f(n) = f(n − 1) ⋅ 2

Have a great day!!

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
