Agroup of students is arranging squares into layers to create a project. the first layer has 6 squares. the second layer has 12 squares. which formula represents an arithmetic explicit formula to determine the number of squares in each layer?

Explicit formula:

Step-by-step explanation:

Let the number of squares in layer be

Given:

Number of squares in first layer,

Number of squares in second layer,

Therefore, the number of squares increases by a factor of 2.

So, it follows a geometric sequence with the first term as 6 and common ratio of 2.

For a geometric sequence, the term with common ratio is given as:

Here,

∴ Explicit formula:
