In an arithmetic sequence, each number is the previous number plus a certain constant. This constant is the common difference. We can find it by taking any number and subtracting the previous number from it. In this case, 26 - 7 = 19 and 45 - 26 = 19. So the answer is B.

Answer: B. 19


Step-by-step explanation:

Given: The values in the table represent a linear function.

We know that common difference in A.P. = difference between consecutive terms in the sequence.

Thus, the common difference = [tex]y_2-y_1=26-7=19[/tex]

Similarly we can check for the other terms as

[tex]y_3-y_2=45-26=19[/tex]

[tex]y_4-y_3=64-45=19[/tex]

[tex]y_5-y_4=83-64=19[/tex]

Therefore, option B is correct, the common difference of the A.P.= 19.
