Answer:
331776
Step-by-step explanation:
The formula for geometric
sequence is given below
ar^n-1
Where a= first term, r= common ratio
From the question, a1 = - 4, r = 6 , n= 5
Then if we substitute, we have
ar^n-1
5th term= ar^n-1
= (-4×6)^(5-1)
=-24 ^ 4
=331776
Hence, the first five terms is =331776
The formula is 5th term= ar^(5-1)
