An airplane flies 617 miles in the morning. then it flies 385 miles in the afternoon. about how many more miles does th airplane fly in the morning?

If you subtract 617 and 385 it will give you the answer which is 232 the plane did 232 in the morning than in the afternoon

Hope it helps :)

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.
