Sathyaram , u must be missing something out like the the no should be integers, or something else

This is becoz infinite such posiibilities r there with such a case.

for example one such series is

0,(7.5),(15)(30) is one of the possible example. infinite other solutions can exist. First mentiion the required condition.
