Evaluate:

Use j = -9 and k = 4

so the way that you would have to solve this is to first do -9*4 which is -36 so then you subtract that from 4 which gives you your answer of:

-40

Hope this helps bye!

Step-by-step explanation:

Hey there!

4 - jk

= 4 - (-9)(4)

= 4 - (-36)

= 4 + 36

= 40

40

Good luck on your assignment and enjoy your day!

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
