Is the last set of numbers meant to be >2.2 <2.5??
.
Panthro, the numbers and symbols in each pair do not point to a specific number, it more describes a specific range - however, the paired numbers are related to the other two such that if one changes either an element of one or indeed both, then the other pairs naturally have to change.
I have just dropped a pretty big clue but I better let you know what that clue is because it's not obvious.
I used the description, 'range' above which describes the mathematical nature of each pair.
It is necessary to have two numbers which should now be obvious when describing a range.
The trick is to guess the nature of this triplet of pairs with 'nature' being the operative word
As to the identity of the two members of our forum who I thought maybe able to solve this?
I think Adam [Bolter] has got a pretty good chance but maybe RebelTackleberry will have something to say in who claims the honour of the fifty quid donation to the NSPCC.
Time will tell no doubt ..... Oh, that wasn't a clue by the way !!
PS I've slightly changed the numbers/symbols on a couple of the pairs - The original sets were accurate syntactically but I've made them more precise, the numbers themselves haven't been changed, the symbols have, such that there is a commonality of use which makes it more consistent and more precise, overall.
Good luck to any prospective Einsteins
