The second term is 8 and the fifth term is -27. Find a1 in this geometric sequence.

Now the Geometric sequence

Step-by-step explanation:

Step(i):-

Given second term is '8'

                         a r = 8 ...(i)

And also given  fifth term is -27

                        ...(ii)

Step(ii):-

   Now  simplify

On simplification, we get

  now from(i)

              a r = 8

Now the Geometric sequence

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8  

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
