Maths Puzzles With Answers #33










Solution:-


it follows this equation 3^n – 2^n where n is integer starting from 0
thus


                     3^0 – 2^0 = 1 – 1 = 0

                     3^1 – 2^1 = 3 – 2 = 1

                     3^2 – 2^2 = 9 – 4 = 5

                     3^3 – 2^3 = 27 – 8 = 19

                     3^4 – 2^4 = 65

                     3^5 – 2^5 = 211

                     3^6 – 2^6 = 729 – 64 = 665



There is one more way to solve this

                   3*previous number + 2^(n-1)

                           0x3+1=1;

                           1×3+2=5;

                           5×3+4=19;

                           19×3+8=65;

                           65×3+16=211;

                           211×3+32=665;


So Answer is 665
