Final answer:

The closed form formula for a geometric sequence is an = a * r(n-1).

Step-by-step explanation:

The closed form formula for a geometric sequence with a first term 'a' and a common ratio 'r' is given by:
an = a * r(n-1)

In the given options,
a) 3*4(n-1) matches the closed form formula for a geometric sequence.
b) 2(n+2), c) 5n, and d) 10(2n-1) are not in the form of the closed form formula for a geometric sequence.
