The fifth term of an arithmetic sequence is 23 and the 12th term is 72 Determine the first three terms of the sequence ​

Step-by-step explanation:

a₁₂ = a₅ + (12-5)d

72 = 23 + 7d

d = 7

a₃ = a₅ + (3-5)d = 23 - 2⋅7 = 9

a₂ = a₃ - d = 9-7 = 2

a₁ = a₂ - d = 2 -7 = -5

answer is more than one

step-by-step explanation:

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
