### Which number will come next in the following series?100, 200, 300, 400, 500, ......

600

Step by Step Explanation:
1. Let us find the difference between the numbers in the given series.
2. So, 200 - 100 = 100
300 - 200 = 100
400 - 300 = 100
500 - 400 = 100
3. On observing the difference carefully, we can say that if we keep on adding 100 to the previous number, we can get the next number.
4. So, we will add 100 to 200 to get the next number, i.e., 500 + 100 = 600.
5. Hence, 600 is the number that will come next in the given series.
