I need help PLEASE A group 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?

a. f(1) = 4; f(n) = 4 ⋅ d(n − 1), n > 0
b. f(1) = 4; f(n) = 4 ⋅ d(n + 1), n > 0
c. f(1) = 4; f(n) = 4 + d(n + 1), n > 0
d. f(1) = 4; f(n) = 4 + d(n − 1), n > 0

Which mathematical statements are true? 1) if 3 is an odd number, then 3 times 3 is an even number. 2) if 6 is less than 7, then 4 is greater than 7. 3) six is divisible by 3, and 10 is a multiple of 2. 4) the average of the data is greater than the largest value in the data, or it’s less than the largest value in the data. 5) the slope of a linear graph is its rate of change, and the graph’s y-intercept is the initial value. 6) if an equilateral triangle has equal angles, then all its angles will measure 45°.
