Sequence obtained from irrational number like 1.618...? (5)
I believe the answer is:
ratio
'sequence' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'irrational number like 1 618 ?' is the wordplay.
'RATIO' is hidden in amongst the letters.
But, I'm unsure how this is indicated.
'obtained from' acts as a link.
Can you help me to learn more?
(Other definitions for ratio that I've seen before include "E.g. two to one" , "Comparative size" , "allowance" , "Quotient of two numbers" , "Expression of relationship" .)
