a dailly farmer produce 50 tons of rice in the first day, 57 tons in the second day, and 64 tons in the third day. the production continue to increase in the same manner up to the 28 day. what is the
a) production of the farmer on the 28 day?
b) what is the total production of the farmer during this period

looks like an arithmetic sequence with
a = 50
d = 7
a) term(28) = a + 27d = 50 + 27(7) = ....
b) sum(28) =
you should have a formula for that.
