If the term of an arithmetic progression is and the term ,show that is
Books are not written by the great Authority. They are written by humans.
Prove it out. An arithmetic progression has a starting value (call it 'a') and a constant difference (call it 'd').
"the pth term is 1/q"
a + (p-1)d = 1/q
"the 9th term is 1/p"
a + (9-1)d = 1/p
This leads to
p*q is going to have to be an integer. You tell me how this can be and then the implications of the result.
