Answer: aₙ = 3 + 4ⁿ⁻¹

So the formula would be:

<u>aₙ = 3 + 4ⁿ⁻¹</u>

Where a₁ = 3

Common Ratio (r) = 4

And n = the term number that needs to be found out

Step-by-step explanation:

<u>Let's check if the answer is right:</u>

To find the 1st number in the term we can substitute 1 in for n in the equation:

a₁ = 3 + 4¹⁻¹

a₁ = 3 + 4⁰

a₁ = 3 + 1

a₁ = 4

And if going back and checking the first number in the sequence given is indeed 4, therefore this equation is correct

Hope this helps!

Find the slope of the line
Schach [20]

Answer:

The slope of the line is: 3

Step-by-step explanation:

Given the points

(-3, -6) and (3, 12)

Determine the slope between (-3, -6) and (3, 12) using the formula

m=\frac{y_2-y_1}{x_2-x_1}

where

m is the slope between (x₁, y₁) and (x₂, y₂)

In our case,

  • (x₁, y₁) = (-3, -6)
  • (x₂, y₂) = (3, 12)

now substitute (x₁, y₁) = (-3, -6) and (x₂, y₂) = (3, 12) in the slope formula

m=\frac{y_2-y_1}{x_2-x_1}

m=\frac{12-\left(-6\right)}{3-\left(-3\right)}

m=\frac{12+6}{3+3}

m=\frac{18}{9}

m=3

Therefore, the slope of the line is: 3

Viktor [21]

Answer:

\frac{3}{4}

Step-by-step explanation:

Total number of the students in the pep squad = 12 students

The number of the students wearing white shirts = 3 students

The number of the students wearing blue shirts = 6 students

Either white or blue shirts indicate that the students wearing white shirt or blue shirt.

Thus, number of students wearing either white or a blue shirt = 3 + 6 students = 9 students
