1/89...Since you mentioned 89 as a Fibonacci number:<br />1/89 = 0.011235...<br /><br />I don't know of any Pythagorean triples with 89, but I know the following works:<br />a^2 - b^2, 2ab, a^2 + b^2<br /><br />Every odd number can be written as a difference of consecutive squares, so there must be a choice for a^2 - b^2 = 89.<br />89 is the 45th odd number; so how about: 45^2 - 44^2 = (45+44)(45-44) = 89(1) = 89. Yes!<br /><br />This worked with a=45, b=44; so the triple is:<br />89, 3960, 3961<br /><br />Hmm... and 89 = 64 + 25 = 8^2 + 5^2 ...<br /><br />Somehow, the smaller numbers arrived later!<br /><br />Here we have a=8, b=5; so the triple is:<br />39, 80, 89<br /><br />MQAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-8268773079578019071.post-55567760606679397112015-08-23T22:47:42.225-05:002015-08-23T22:47:42.225-05:00What a great collection!!
