t(n) = 6*n - 1 where n = 1, 2, 3, ...
11, 14, 19, 26 and 35.
Let the numbers by 'm' & 'n' Hence m + n = 12 mn = 35 Hence m = 35/n Substitute 35/n + n = 12 Multiply through by 'n' 35 + n^2 = 12n n^2 - 12n + 35 = 0 It is now in Quadratic Form ; Factor ( n - 7)(n - 5) = 0 Hence n= 7 or n= 5 It follows that m = 5 , or m = 7
The simplest and most obvious sequence is given by the formula: X[n]=136 - n*7 This gives X[11]=59.
47 and 53. This sequence can be 6n+5. For n= 2,3,4,5,6,7 etc.
