    5. Find the difference of the production during 7th year and 4th
    year.

    Answer:
    1. Rs 5000
    2. Production during 8th year is (a+7d) = 5000 + 2(2200) = 20400
    3. Production during first 3 year = 5000 + 7200 + 9400 = 21600
    4. N = 12 5.
    5. Difference = 18200 - 11600 = 6600
