What is the fifth term of the linear sequence which begins 20, 14, 8

Mathematics
1 answer:
JulijaS [17]2 years ago
3 0

Answer:

The fifth term is -4

Step-by-step explanation:

The sequence has a common difference therefore, it is an arithmetic sequence

The formula for arithmetic sequence is

an = a1 + (n - 1)d

<em>where,</em>

<em>an is the nth term,</em>

<em>a1 is the first term,</em>

<em>n is the term number and</em>

<em>d is the common difference</em>

<u>Find the 5th term.</u>

an = a1 + ( n-1 ) d

a5 = 20 + ( 5-1 ) -6

a5 = 20+ ( -24 )

a5 = -4

If y = kx, and x = 3 and y = 15, calculate k.
kenny6666 [7]

Answer:

k = 5

Step-by-step explanation:

Since the equation is y = kx and x equals 3 while y equals 15, in order to solve this equation we are going to have to substitute the variables with their answers:

x = 3

y = 15

15 = 3k

Now we divide 3 from both 3x and 15 to segregate the variable x:

15/3 = 3k/3

5 = k

Now to check our work we are going to substitute 5 for the variable k, 3 for the variable x and 15 for the variable y.

y = kx

15= (5)(3)

15 = 15

Tada, I hope this helps you!

Find the value of x..helppp
alekssr [168]

Answer:

For the diagram to be a parallelogram, then the measure of x is 4

Step-by-step explanation:

If the diagram is a parallelogram, then the diagonals bisect each other

What this mean is that they divide each other into 2

Mathematically, this means that the values AC is divided into two equal parts AE and CE

That means;

5x + 28 = 3x + 36

5x-3x = 36-28

2x = 8

x = 8/2

x = 4
