Which of the following is the beginning of an arithmetic sequence?

   b.  22, 28, 34, 40

Step-by-step explanation:

This is the only sequence with a common difference, hence the only arithmetic sequence: 22, 28, 34, 40 (common difference of 6).

___

When adjacent terms of the sequence have the same difference, the sequence is arithmetic. When adjacent terms have the same ratio, the sequence is geometric. (Only a non-zero constant sequence will be both.)

step-by-step explanation:

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.
