Doug created a pattern of towers. Tower 1 was created using 5 blocks. Tower 2 used 6 blocks. Tower 3 used 7 blocks. Tower 4 used 8 blocks. what is the rule for the pattern Doug used to build his towers? How many blocks will be in Tower 20
Each tower contains one more block than the one before. Since Tower 1 has 5 blocks, wouldn't Tower 20 contain 5 + 20 blocks?
