Step-by-step explanation:
The answer is true.
For example lets say the numbers given are 1, 5, 9, ...
To find the common difference, you subtract the 1st term from the 2nd term. In this case, we would do 5 - 1, which equals 4.
We must add the common difference to the last term in order to find the next term. Since the common difference is 4, we add 4 to 9, which makes 13. This applies only in the arithmetic sequence.
Answer: Mean is 12
Step-by-step explanation: Mean is adding it all up and then dividing, 12 + 13 + 11 + 11 + 13 is 60
Divide 60 by the amount of numbers, 5
60 divided by 5 is 12
