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.

Answer:
7.5 meters/second
Step-by-step explanation:
Speed = the magnitude of distance / time
Distance = 33 meters
Time = 4.4 seconds
Speed = 33 meters / 4.4 seconds = 7.5 meters/second. This is already to the tenths place, or the place right after the decimal, so we don't have to worry about rounding here.
