Answer:

Geometric

Exponential

a_n=2(6)^{n-1}

a_n=6a_{n-1} with a_1=2

Step-by-step explanation:

Arithmetic sequences have a common differences.

This is not arithmetic because 12-2 is not the same as 72-12. One is 10 while the other is 60.

Geometric sequences have a common ratio.

This is geometric because 12/2 is the same as 72/12.  They are both 6.

Arithmetic sequences are linear.

Geometric sequence are exponential.

Since this is a geometric sequence, then is is exponential.

a_1 means first term.

a_{n-1}[tex] means the previous term to [tex]a_1.

The arithmetic sequences have explicit form: a_n=a_1+d(n-1)

The arithmetic sequences have recursive form: a_n=a_{n-1}+d with a_1 given.

d represents the common difference.

The geometric sequences have explicit form: a_n=a_1(r)^{n-1}

The geometric sequences have recursive form: a_n=r a_{n-1} with a_1 given.

r is common ratio.

So since it geometric, then the explicit formula is a_n=2(6)^{n-1} and the recursive form is a_n=6 a_{n-1} with a_1=2.
