**tchrwill**, Sunday, November 15, 2009 at 9:53amWhat value of p are 2p-1, 7 and 3p three consecutive terms of an ARITHMETIC PROGRESSION?

Letting a = the common difference, we can write

1--(7 - a) = 2P - 1 and

2--(7 + a = 3p

Adding yields 14 = 5p - 1 from which p = 3 making the 3 terms 5, 7 and 9.
