Would dearly appreciate some help with this...
Firstly, are the first 2 digits of 11a. 1, 5?
Secondly, is the 'segmenting into 3 numbers, where one of them is the sum of the other two' achieved by dividing them into 3 double digit numbers as outlined below?
For example, if 11a. was 1,5,8,2 - then would the 3 segmented no.'s would be 15 - 58 - 82.
It's just I can't find any 2 no's that follow 1 and 5 (Excluding 3,4,7 and 0) that when split into 3, as above, meet the criteria. Obviously 1 might not be the first number but I've checked 1d. 3 times now and every time get the same answer, namely one where 1 is the middle number.
