Answer:
Step-by-step explanation:
The numbers don’t increase by a constant amount, so this is not an arithmetic sequence.
It appears to be a <em>geometric sequence</em>.
The <em>general formula</em> for each term in a geometric sequence is
aₙ = a₁rⁿ⁻¹
===============
Calculate the value of r
You can calculate the r-value by dividing any two consecutive terms in the sequence.
rₙ = aₙ/aₙ₋₁
a₂/a₁ = 4.5/3 = 1.5
a₃/a₂ = 6.75/4.5 = 1.5
a₄/a₃ = 10.125/6.75 = 1.5
a₅/a₄ = 15.1875/10.125 = 1.5
r = 1.5
===============
Determine the formula for the nth term
a₁ = 3; r = 1.5 Substitute the values
aₙ = 3(1.5)ⁿ⁻¹ Write the equation as a function of x

Answer:
Step-by-step explanation:
There are two options as below.
1. JL/JK = 5 : 1
<u>Find the coordinates of L:</u>
- x = -2 + 5/6(10 - (-2)) = -2 + 10 = 8
- y = 10 + 5/6(-14 - 10) = 10 - 20 = - 10
The point is L(8, - 10)
2. JL/JK = 1 : 5
<u>Find the coordinates of L:</u>
- x = -2 + 1/6(10 - (-2)) = -2 + 2 = 0
- y = 10 + 1/6(-14 - 10) = 10 - 4 = 6
The point is L(0, 6)
The answer should be x=-2
