To determine the total amount of money you will have in 12 months by following this savings pattern, we can use a formula for a geometric progression:

Sn = a * (r^n - 1) / (r - 1)

Where:
- Sn refers to the sum of the geometric progression,
- a refers to the first term,
- r refers to the common ratio, and
- n refers to the number of terms.

In this case:
- The first term (a) is $2.
- The common ratio (r) is 2, as each subsequent month's savings doubles.
- The number of terms (n) is 12, as you save for 12 months.

Plugging these values into the formula, we can calculate the sum of the geometric progression:

Sn = 2 * (2^12 - 1) / (2 - 1)
= 2 * (4096 - 1) / 1
= 2 * 4095
= 8190

Therefore, after 12 months of following this savings pattern, you will have $8190.
