Let there be the first nine terms of an arithmetic sequence with the first term a1=1 and the difference d=1. Suppose we are creating ordered triples of 3 different numbers out of the given 9 numbers so that they form 3 consecutive terms of a geometric sequence. How many of such triples can be created?
