What is the value of the fourth term in a geometric sequence for which a1 = 30 and r = 1/2?
Pani-rosa [81]

Answer:  The required fourth term of the geometric sequence is \dfrac{10}{9}.

Step-by-step explanation:  We are given to find the value of the fourth term in a geometric sequence with first term and common ratio as follows :

a(1)=30,~~~~~r=\dfrac{1}{2}.

We know that

the n-th term of a geometric sequence with first term a1 and common ratio r given by

a(n)=a(1)r^{n-1}.

Therefore, the fourth term of the given geometric sequence will be

a(4)=a(1)r^{4-1}=30\times r^3=30\times\left(\dfrac{1}{3}\right)^3=\dfrac{30}{27}=\dfrac{10}{9}.

Thus, the required fourth term of the geometric sequence is \dfrac{10}{9}.
