The two consecutive numbers after 5009 are
A) 5010, 5020
B) 50010, 50011
C) 5010, 5011
D) 5010, 5012

Hint: Here, we will use the fact that the consecutive numbers are number one after another. So we will keep on adding the number with one as per asked in the question.

Complete step by step solution: We are given that the number is 5009.

We know that the consecutive numbers can be obtained by adding one to the previous number.

First, we will compute the next consecutive number after 5009 by adding one.

\[ \Rightarrow 5009 + 1 = 5010\]

We can add one to the above number to find the next consecutive number after 5010.

\[ \Rightarrow 5010 + 1 = 5011\]

Thus, the two consecutive numbers after 5009 are 5010, 5011.

Hence, option C is correct.

Note: While solving these types of problems, students should know about consecutive numbers. This is a really simple question, we just have to keep on adding the number by one as asked. One can also solve this question by using that a predecessor of a given number is the number that comes just before a number which is 1 less than the given number and successor of a given number is the number that comes just after a number which is 1 more than the given number. So we will find the successor of the number 5009 by adding 1.
\[ \Rightarrow 5009 + 1 = 5010\]
We can add one to the above number to find the next consecutive number after 5010.
\[ \Rightarrow 5010 + 1 = 5011\]
Thus, the two consecutive numbers after 5009 are 5010, 5011.
