If the first gardener can finish the job in 6 hours, it means that every hour he completes 1/6 of the job.
By the same logic, the second gardener completes 1/7 of the job per hour.
So, if they work together, they complete
of the job per hour.
So, after 42/13 of a hour, they'll complete the job. Since one hour is made of 60 minutes, 42/13 of a hour is
So, it will take them about 194 minutes to finish the job, i.e. about 3 hours and 14 minutes.

In an arithmetic sequence d represent the common difference.
The formula to find the general term of an arithmetic sequence is,
Where = nth term and
= First term.
Given, . Therefore,
Next step is to subtract the above equations so that we can eliminate a1 and get the value of d. Hence,
4d - 8d = 24 - 40
-4d = - 16
Divide each sides by - 16.
d = 4
So, d = 4.
Hope this helps yoi!.
