What are Consecutive Numbers - Example of Consecutive numbers

What are Consecutive Numbers ? Consecutive numbers are numbers that follow each other in order from smallest to largest. In other words, we can say that consecutive number of any number is obtained by adding 1 to the that number. Question : - Write the three consecutive numbers occuring just after 157. Explanation : - The next three consecutive number of 157 can be obtained by adding 1, 2 and 3 to 157 that is, 157 + 1 = 158 157 + 2 = 159 157 + 3 = 160 Hence the three consecutive number occurring just after 157 are 158 , 159 and 160 respectively.
