y=x is a linear function. This is the only function not to a power
the explicit formula for aₙ the nth term of the sequence will be:
Step-by-step explanation:
The explicit formula of geometric sequence is of the form:

where a₁ is the first term and r is the common ratio.
We are given:
a₁ = 6
r = 2/3
Putting values in the formula:

So, the explicit formula for aₙ the nth term of the sequence will be:
