2x+12=6x-12 show all work

Mathematics

First off we want to combine "like-terms"
1. Subtract 6x , so it will look like this: 2x-6x+12=-12
2. Subtract the -12 from the first side so it looks like 2x-6x=-12-12
3. Combine like terms. So: -3x=-24 . The negatives will cancel out when dividing 24/3.

The final answer is 8 after dividing. Hope this helped!

Show how the following sequences is an arithmetic or not <br>please help me ​
serious [3.7K]

Answer:

not arithmetic

Step-by-step explanation:

An arithmetic sequence has a common difference d between consecutive terms.

Given

T_{n} = 2n² - 1

Substitute in n = 1, 2, 3, 4 to generate the first 4 terms of the sequence

T_{1} = 2(1)² - 1 = 2 - 1 = 1

T_{2} = 2(2)² - 1 = 8 - 1 = 7

T_{3} = 2(3)² - 1 = 18 - 1 = 17

T_{4} = 2(4)² - 1 = 32 - 1 = 31

check the difference between consecutive terms

7 - 1 = 6

17 - 7 = 10

31 - 17 = 14

The differences are not common hence not an arithmetic sequence
