5n+3/4n=2
20n+3n/4=2
23n/4=2
23n=8
n=8/23
I believe it is the bottom one, spanning -6 to 6
The absolute value is the distance from the number to 0
The absolute value of 6 is 6 and the absolute value of -6 is 6 because they are both 6 values away from 0
Question 1
You can see that each term is obtained from the previous one by subtracting 8. Starting from 30, we subtract 8 to get 22. Then, we subtract 8 to get 14, and we subtract 8 to get 6.
So, the next three terms will be given by subtracting 8 again and again:
Correct answer: D
Question 2
The sequence starts with 4, and so option is surely wrong. Every next term is given by doubling the previous one: starting with 4, we double it to get 8; we double it it get 16, and finally we double it to get 32.
Correct answer: A
Question 3
In order to find the first four terms of the sequence, we have to plug the values in the equation: we have
Correct answer: B
