1. Which of the following is the 65th term in the sequence 8, 5, 2,-1, A.-184
B. -186
C. -190
D. -195​

-184

Step-by-step explanation:

8,5,2,-1...

a=first term=8

Common difference=T2-T1=T3-T2=T4-T3

5-8=2-5=-1-2=-3

T65=a+64d

T65=8+64(-3)

T65=8-192

T65=-184

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
