Answer:

-1, 9, - 21, 69

Step-by-step explanation:

Given recursive formula:

a₁ = -1
aₙ = - 3aₙ₋₁ + 6 for n ≥ 2

The first 4 terms are:

a₁ = - 1, given
a₂ = - 3*(-1) + 6 = 3 + 6 = 9
a₃ = - 3*(9) + 6 = - 27 + 6 = - 21
a₄ = - 3*(-21) + 6 = 63 + 6 = 69

natali 33 [55]

Answer:

2.5 times

Step-by-step explanation:

From the diagram attached below;

let's calculate the volume of each bottle;

SO for bottle X;

we have ;

Volume of X = $\dfrac{1}{2}*2*1*6$

Volume of X = $6 \ \ in^3$

Volume of Y = $\dfrac{1}{2}*3*2.5*4$

Volume of Y = $15 \ \ in^3$

The ratio of Y to X can help us to determine how many times more lotion is in Bottle Y than in Bottle X; So taking their ratio ; we have:

$\mathbf{\dfrac{volume \ of \ Y }{volume\ of \ X} = \dfrac{15}{6} }$

= 2.5 times

Thus; Bottle Y has 2.5 times more lotion than Bottle X
