Calculation of Camel's Steps

To calculate the number of steps the camel took on the ninth day, we need to analyze the pattern of increasing steps each day.

According to the given information, the camel walks an increasing number of steps each day. On the first and second days, it walked 2050 steps, and on the seventh and eighth days, it walked 2170 steps.

To find the number of steps the camel took on the ninth day, we need to determine the pattern of increase in steps.

Let's analyze the difference in steps between consecutive days:

- From the first to the second day, the camel increased its steps by 0. - From the second to the seventh day, the camel increased its steps by 2170 - 2050 = 120. - From the seventh to the eighth day, the camel increased its steps by 0.

Based on this pattern, we can conclude that the camel increases its steps by 120 each time, except for the days when the increase is 0.

To find the number of steps the camel took on the ninth day, we can calculate the difference between the steps on the eighth and ninth days and add it to the steps on the eighth day.

Let's calculate it:

Steps on the eighth day: 2170. Increase in steps from the eighth to the ninth day: 120.

Therefore, the number of steps the camel took on the ninth day is:

2170 + 120 = 2290 steps.

So, the camel took 2290 steps on the ninth day.
