Agroup of students is arranging squares into layers to create a project. the first layer has 4 squares. the second layer has 8 squares. which formula represents an arithmetic explicit formula to determine the number of squares in each layer?
a1 = 4; an = 4 ⋅ an − 1, n > 0
a1 = 4; an = 4 ⋅ an + 1, n > 0
a1 = 4; an = 4 + an + 1, n > 0
a1 = 4; an = 4 + an − 1, n > 0
