Look at the number line.
155 is between
154 and 156.
151 comes before 152. 159 comes after 158.
150 151 152 153 154 155 156 157 158 159 160
• 151 comes before 152. It is the predecessor of 152. To find the predecessor
of a number, we subtract 1 from the number (152 – 1 = 151).
• 159 comes after 158. It is the successor of 158. To find the successor of a
number, we add 1 to the number (158 + 1 = 159).
• 155 is between 154 and 156.
