<PRE><B>Question 857752</B>
can you help me to find three numbers which are in arithmetic series and in geometric series and the common difference or common ratio should not be zero
------
Arithmetic Sequence:: a, a+d, a+2d
--------
If that is also a geometric sequence,
(a+d)/a = (a+2d)/(a+d)
-------
(a+d)^2 = a(a+2d)
------
a^2 + 2ad + d^2 = a^2 + 2ad
-----
d^2 = 0
d = 0
-----
Then the arithmetic sequence = a,a,a
which is not an aritmetic sequence.
------
Answer to your question.  There is no answer.
