Hello, bond!
Does it really help to write things in a different color and in a smaller font?
And if you have no idea what's going on, why are you working on this problem?
I assume this is a Fibonacci-type sequence . . .Can you please help me to obtain the generating function of the recurrence relation
ar =ar-l + ar-z with ao = 0, al = 2, az = 3. . . . this is wrong!
. . Each term is the sum of the preceding two terms.
The sequence is: .
The terms are exactly twice that of the original Fibonacci sequence
. . whose formula is: .
Therefore: .
Does that help?
I didn't think so . . .
