Answer correct for brainliest and also get a ! : -) answer a and b!

a) your iterative rule would be: 22,28,34,40 it is because there are 22 in first row and it is increasing by 6 at each step

b) Now, a(n) = 100, a=22, d=28-22 = 6

we know, a(n) = a+(n-1)d

 100 = 22+(n-1)6

 100-22 = 6n-6

  78+6 = 6n

  n = 84/6

  n= 14

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold
