Find the 4th term in the sequence

Mathematics
1 answer:
kodGreya [7K]2 years ago
8 0

The sequence an = 2(an-1 - 3) is a recursive sequence

The 4th term of the sequence is -42

<h3>How to determine the 4th term?</h3>

The given parameters are:

a1 = 0

a2 = -6

an = 2(an-1 - 3)

Start by calculating a3 using:

a3 = 2(a2 - 3)

This gives

a3 = 2 * (-6 - 3)

a3 = -18

Calculate a4 using:

a4 = 2(a3 - 3)

This gives

a4 = 2 * (-18 - 3)

a4 = -42

Hence, the 4th term of the sequence is -42

Volume of a pyramid is (L * w * h) / 3

L=10 and w=10

h can be found by using the Pythagorean theorem:

divide the base by 2 and we get 5. Then we have that the hypotenuse is 13 and the bottom of the right triangle we formed is 5. a= sqrt(c^2-b^2)

a=h=12

we plug these numbers into the formula for the volume of a pyramid and get:

Linear Equation In One Variable<br>solve x,3/2-7=5​
Karo-lina-s [1.5K]

Question:

Linear Equation In One Variable

solve x,

\frac{3x}{2} -7 = 5

Answer:

x = 8

Step-by-step explanation:

Given

\frac{3x}{2} -7 = 5

Required

Solve for x

\frac{3x}{2} -7 = 5

Multiply through by 2

2(\frac{3x}{2} -7) = 5 * 2

2*\frac{3x}{2} -2 * 7 = 5 * 2

3x - 14 = 10

3x = 14 + 10

3x = 24

Solve for x

x = \frac{24}{3}

x = 8
