Question

What is the initial value of the sequence?

Answer 1

Answer:

The initial value of the given geometric sequence is 2.

Step-by-step explanation:

The given points are (1,2), (2,4) and (3,8).

It means the first term is 2, second term is 4 and third term is 8. So, the common ratio is

$r=\frac{a_2}{a_1}=\frac{4}{2}=2$

A geometric sequence is defined as

$f(n)=ar^{n-1}$

Where, a is first term of the sequence, r is common ratio and n is number of term. In other words f(1) is the initial value of the geometric sequence.

The given geometric sequence is

$f(n)=2(2)^{n-1}$

The value of f(1) is 2.

Therefore the initial value of the given geometric sequence is 2.
