Find the common difference of the arithmetic sequence -6, -13, -20,...

Common difference = 2nd term - first term

= -13-(-6)

= -13+6

= -7

-7

Step-by-step explanation:

arithmetic sequences are consistant sequences by adding or subtracting a constant term, in this case to get from -6 to -13, you subtract 7. And to get from -13 to -20 you subtract 7 again. The next number in the sequence would be -27 as -20-7= -27

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
