Read the following passage:

India is competitive manufacturing location due to the low cost of manpower and strong technical and engineering capabilities contributing to higher quality production runs. The production of TV sets in a factory increases uniformly by a fixed number every year. It produced 16000 sets in 6th year and 22600 in 9th year.

  1. In which year, the production is 29,200 sets?
  2. Find the production in the 8th year.
    OR
    Find the production in first 3 years.
  3. Find the difference of the production in 7th year and 4th year.
