first three images in the pattern. her teacher said the
images were created by taking a red square, dividing it into 9 smaller squares, and removing the center
a. joyce's teacher asks her to write the sequence formed by the number of red squares in each picture for the first
five pictures. what sequence should joyce write?
b. is this sequence arithmetic, geometric, or neither? how do you know?
c. joyce's teacher asks her to also write the sequence formed by the area of 1 red square in each picture for the first
five pictures. assume the original square has an area of 1 square unit. what is the sequence of areas for a single
red square for the first five pictures?
d. is this sequence arithmetic, geometric, or neither? how do you know?
