I am not sure what I suppose to do ​

put values of x in the equations above the boxes and write the answer in y column

I'm pretty sure that you need to subsitute the values for x into the equations. For example, if the equation is y=x-7, you should start by putting 2 in for x (y=2-7). This would mean that your answer is -5. Is that what you were asking?

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
