4. Juan took a pencil and drew two squares, the next row he drew six squares, then the third row he drew eighteen squares. If he kept this pattern up (and had the space), how many
squares would he draw in the 11th row?
a. f(n)= 3(2)"+1; 3072 squares b. f(n) = 2(3): 118,098 squares
c. f (n) = 2(3): 354, 294 squares d. F(n) = 3(2)-1; 6, 144 squares

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
