Let k = the constant amount added to the sequence since this
is an arithmetic sequence
x = missing
number
You have to formulate an equation based on the sequence:
6 + k = x or k = x – 6
x + k = 30
Substitute the value of k to the second formula:
x + x – 6 = 30
2x = 36
x = 18
Therefore, the missing number is 18.

3 might be incorrect but The others seem more correct than ever :)
Answer:
x=0.936
Step-by-step explanation:
You convert it to feet. There are 5,280 feet in a mile. Then convert it to inches. 5,280 feet multiplied by 12 (since there are 12 inches in a foot) is 63,360.
So... 1 mile= 5,280 feet
5,280 feet= 63,360 inches
and so
1 mile= 63,360 inches
