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

Answer 1

Each tower contains one more block than the one before. Since Tower 1 has 5 blocks, wouldn't Tower 20 contain 5 + 20 blocks?
