1) Write an expression to represent the pattern.

19, 27, 35, 43 ...

A: y = 11x + 8

B: y = 8x + 11

C: y = 19x

D: 8x = 11

2) Write an expression to represent the sequence.

71, 62, 53, 44 ...

A: y = 9x + 80

B: y = 9x + 71

C: y = - 9x + 80

D: y = - 9x + 71

1. B 2. C

Step-by-step explanation:

1. B is the answer because if you add 8 times 1 to 11 you get 19 and if you add 8 times 2 to 11 you get 27 so that is the expression to represent the pattern.

2. C is the answer because if you add - 9 times 1 to 80 you get 71 and if you add - 9 times 2 to 80 you get 62 so that is the expression to represent the pattern.
