Consider the pattern shown by the following arrays of square tiles: Note: An unshaded square is a white tile and a shaded square is a blue tile. List the sequence of terms that represent the number of blue (shaded) square tiles in each array. Mr. Ihe pattern continues, determine the next two terms in the sequence. Write a formula for the number of blue (shaded) square tiles in the n-th array.
