z=17

Explanation:

just took the test and got them right

Answer 2

ANSWER


`x = 3`


`y = 10`


`z = 17`

EXPLANATION

The rule for the sequence


`a_n=-4+(n-1)7`

When n=2,


`a_2=-4+(2-1)7`


`a_2=-4+7 = 3`


`x = 3`

When n=3,


`a_3=-4+(3-1)7`


`a_3=-4+14 = 10`


`y = 10`

When n=4,


`a_4=-4+(4-1)7`


`a_4=-4+21 = 17`


`z = 17`
