The common difference in an arithmetic sequence refers to the number that represents the difference between two terms in the sequence.
When you look to the sequence you can see that from a term to other one the numbers are increasing, meaning that the common difference needs to be positive. To find the value of the common difference in an arithmetic sequence you have to select two terms. On this case 2.5 and 6, and 16.5 and 20.
Common Difference= 6-2.5
Common Difference= 3.5
Common Difference= 20-16.5
Common Difference= 3.5
After some calculations, you can conclude that the number representing the common difference in this arithmetic sequence is 3.5.

Its to long to explain but thats the answer
Answer:
The probability is 3/10, or 30%.
Step-by-step explanation:
A probability P is the ratio of the number of favorable (relevant) cases and the total number of all possible cases.
The probability that Red and Small is selected can be estimated using values from the table:
P(Red and Small) = #(Red and Small) / # (total) = Value(2nd row, 2nd column) / Sum (all cells in the table) = 12/40 = 3/10 = 30%.
