six wooden poles used as electric poles are position in an arithmetic sequence. if the position of the 2nd and 6th poles from the station are 2 and 5 respectively find the position of the other poles
(6-2)d = 5-2
so d = 3/4
so the sequence is
2 - 3/4, 2, 2+3/4, 2+6/4, 2+9/4, 5
5/4, 2, 11/4, 14/4, 17/4, 5
