Answer:

9, 18, 27, 36, ... is an arithmetic sequence.

Last option is correct.

Step-by-step explanation:

In Arithmetic sequence the difference of two consecutive terms is equal and we called this difference as common difference.

Therefore, we check in which the difference of two consecutive terms is equal.

For 1st sequence

6, 12, 15, 21, ...

12-6 = 6

15-12 = 3

The difference is not equal. Hence, it is not an arithmetic sequence.

For 2nd sequence

7, 14, 21, 36, ...

21-14=7

36-21=15

The difference is not equal. Hence, it is not an arithmetic sequence.

For 3rd sequence

8, 16, 32, 64,.....

16-8=8

32-16=16

The difference is not equal. Hence, it is not an arithmetic sequence.

For 4th sequence

9, 18, 27, 36, ...

18-9=9

27-18=9

The difference is equal. Hence, it is an arithmetic sequence.

Therefore, 9, 18, 27, 36, ... is an arithmetic sequence.

Last option is correct.

Answer:

22, 25, 28, 31

Step-by-step explanation:

The question is mixed up. The only clear question is:

Given:

4, 7, 10, 13, 16, 19

Required

Write the next 4

Notice that the rule of the above sequence is to "add 3". So, the next 4 numbers is gotten by adding 3 to the previous number on the sequence.

The next 4 are:

19 + 3 = 22

22 + 3 = 25

25 +3 = 28

28 + 3= 31

Let A = -4k+ 3 and B = 3k +17. If A = B, then what is the value of k?​
kupik [55]

Answer:

k=-2

Step-by-step explanation:

Using substitution to find what you're missing, (in this case k) is when you plug each letter into the other equation:

-4k+3=3k+17

So now solve for k:

subtract 3 from both sides...

-4k=3k+14

subtract 3k from both sides to combine with -4k...

-7k=14

divide -7 from both sides...

k=-2
