The production of TV sets in a factory increases uniformly by a fixed number every year. In the 3rd year production was 600 sets and in the 7th year it was 700 sets. Find the production in the 1st year.

Question

Accepted Answer

550. a7 - a3 = 4d = 700 - 600 = 100, so d = 25. a3 = a + 2d = 600 gives a = 600 - 50 = 550.
