Answer:
First term: 375
Second term: 375*0.4=150
Third term: 375*0.4*0.4=60
Fourth term: 375*0.4*0.4*0.4=24

Answer:
The sequence begins 3,15,75,375
.Step by step explanation
It is represented as
an=3×5n
.
Explanation:
For a geometric sequence, if
a0=3 and a3=375
, then we can use
an=a0rn
to find
r
. In our case, since we know the 3rd term after the initial term is
a3=375
, and we know the initial term itself is
a0=3
, we use
n=3
and substitute:
a3=a0r3
375=3r3
125=r3
5=r
Now that we know
r
, we can find the missing terms:
a1=a0r=3(5)=15
a2=a0r2=3(5)(5)=75
and
a3=a0r3=3(5)(5)(5)=375
Mot sure about the answer
