Find the missing terms in the following geometric sequence.

Mathematics
2 answers:
Dmitrij [34]3 years ago

Answer: D. 36, 108

Step-by-step explanation:

In the geometric series the ratio of two consecutive term is constant and this ratio is called the common ratio,

Let n be the common ratio of the given series,

Then the GP will be,

12, 12×n, 12×n×n, 324,

Again by the definition of Geometric series,

\frac{12n}{12} = \frac{324}{12n^2} \implies n^3 = 27\implies n = 3

Thus, the required series is,

12, 12×3, 36×3, 324

= 12, 36, 108, 324

⇒ Option D is correct.

Answer:

The correct option is d. 36, 108

Explanation:

We are given the below series:

12,___, ___, 324

In geometric series every number after the first is found by  multiplying the previous term by a fixed number.

The given series can be written as:

12 \times 3^{0}=12

12 \times 3^{1}=36

12 \times 3^{2}=108

12 \times 3^{3}=324

Therefore, the option d. 36, 108 is correct

Answer:

  • x = 4

Step-by-step explanation:

x has the same value as RT since they are equal sides of the isosceles triangle.

RT is also the hypotenuse of ΔRST - 30°×60°×90° right triangle.

Acoording to the property of such triangles, the ratio of sides is:

  • a : b : c = 1 : √3 : 2

We have:

  • b = 2√3 and c = RT

Use the ratio to find the lenght of RT

  • 2√3 : RT = √3 : 2
  • RT = 2*2√3/√3
  • RT = 4

So the value of x is 4 units

(n^3 +67² + 4n - 2)/(n + 1)
Alla [95]

Answer:

(n^3 + 4 n + 4487)/(n + 1)

Step-by-step explanation:

Simplify the following:

(n^3 + 4 n - 2 + 67^2)/(n + 1)

| | 6 | 7

× | | 6 | 7

| 4 | 6 | 9

4 | 0 | 2 | 0

4 | 4 | 8 | 9:

(n^3 + 4 n - 2 + 4489)/(n + 1)

Grouping like terms, n^3 + 4 n - 2 + 4489 = n^3 + 4 n + (4489 - 2):

(n^3 + 4 n + (4489 - 2))/(n + 1)

4489 - 2 = 4487:

Answer: (n^3 + 4 n + 4487)/(n + 1)
