Question

Write the first five terms of the geometric sequence, given a1= -16 and r= -1/4​

Answer 1

Answer: -16, 4, -1, 1/4,?

Step-by-step explanation: the nth term of a GP is given by Un= ar^n-1

Where n= the term.

So substituting the values for each term will give you the answer above. I don't know if it's tiredness or what but my fifth term gives me the same value as my fourth term.
