The first term of the geometric sequence is 2.
What is geometric sequence?
A geometric progression, also known as a geometric sequence, is a sequence of non-zero numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio.
Given
Geometric sequence
---, 4, 8, 16, 32, ---
[tex]a_{2} =2^{2}=4[/tex]
[tex]a_{3} =2^{3} =8[/tex]
[tex]a_{4} =2^{4} =16[/tex]
[tex]a_{5} =2^{5} =32[/tex]
So, [tex]a_{n}=2^{n}[/tex]
Then
[tex]a_{1}=2^{1}=2[/tex]
The first term of the geometric sequence is 2.
