Find the first term and the common difference of the arithmetic sequence described. give a recursive formula for the sequence. find a formula for the n^th term

5th term is 0;
50 term is - 135

1d

2b

3 false

4 d

5 3200sq,ft

80+60+y=180

then divide the difference between 60 and y and add it to 180

so x =180 +( (y-60)/2)

x equals 200
