What is the value of the 9th term in the following geometric sequence?

earnstyle [38]

Answer: The correct option is (D) 196608.

Step-by-step explanation: We are given to find the value of the 9th term in the following geometric sequence :

3, 12, 48, 192, . . .

We know that

the n-th term of a geometric sequence with first term a and common ratio r is given by

$a_n=ar^{n-1}.$

For the given sequence, we have

first term, a = 3 and the common ratio, r is given by

$r=\dfrac{12}{3}=\dfrac{48}{12}=\dfrac{192}{48}=~~.~~.~~.~~=4.$

Therefore, the 9th term of the given sequence will be

$a_9=ar^{9-1}=3\times 4^8=3\times65536=196608.$

Thus, the required 9th term of the given sequence is 196608.

Option (D) is CORRECT.

4x + 6y = 18 & 4x – 2y = 10

kherson [118]

Answer:

x=4.875

y=-0.25

Step-by-step explanation:

4x – 2y = 10

2x-y=10

y=2x-10

4x + 6y = 18

2x+3(2x-10)=9

8x=39

x=4.875

y=2(4.875)-10

y=-0.25
