Answer:
the steady acceleration is 4m/s^2
Explanation:
all you need to do for the speed is add 4 to the last number to get the next one. in your case you want to find the speed after 3seconds and 5 seconds so just add 4 to 8 to get the first one then add 4 to 16 to get second one
1s 2s 3s 4s 5s 6s 7s
4m/s 8m/s 12m/s 16m/s 20m/s 24m/s 28m/s
