Find the sum of an arithmetic
9 terms; 2, 5, 8, 11
9

126

Step-by-step explanation:

the formula for sum of arithmatic progression=n/2(2a+(n-1)d)

=9/2 (4+8*3)

=9/2*(28)

=9* 14=126

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
