in an ap the difference is between the 8th and 4th term is 20 and the 8th term is one and the half times the fourth term what is the common difference
Answered by Steve
since T8 = T4+4d, d=5

and, just for completeness,

a+7d = 3/2 (a+3d)
a+35 = 3/2 (a+15)
2a+70 = 3a+45
a=25

So, the sequence is

25 30 35 40 45 50 55 60 ...
