Explanation:
#"the terms form the terms of an "color(blue)"arithmetic sequence"#
#a,a+d,a+2d,a+3d,......,a+(n-1)d#
#"where a is the first term and d the "color(blue)"common difference"#
#d=a_2-a_1=a_3-a_2=......=a_n-a_(n-1)#
#"here "d=3/8-1/4=1/2-3/8=5/8-1/2=1/8#
#"to obtain any term from the previous term add d to it"#
#rArra_5=5/8+1/8=6/8=3/4#
#rArra_6=3/4+1/8=7/8#
#rArra_7=7/8+1/8=8/8=1#
#rArra_8=1+1/8=9/8#
