Answer:
a3 = 32
Step-by-step explanation:
The sum of the first n terms of a geometric sequence is called geometric series. The given nth term formula helps in finding out any term in the specified geometric sequence.
To calculate the 3rd term, we will substitute n = 3 into the formula.
Thus,
a3 = 2(4)³-1
a3 = 2(4)²
a3 = 32
Thus the third term of the sequence will be 32
