Question

Help please. Medals are given.
Generate the first 5 terms of this sequence:

f(1) = 0 and f(2) = 1, f(n) = f(n - 1) + f(n - 2), for n > 2.

0, -1, 1, 0, 2

0, 1, 1, 2, 3

0, 1, 2, 2, 3

0, 1, 1, 2, 2

Answer 1

u can see that f(1)=0 and f(2) =1
so the first two turm is
0,1
so a is not correct now find
f(3)=f(3-1)+f(3-2)=f(2)+f(1)=1+0=1
so u have now the first three elements
0,1,1
so c is not correct now find
f(4)=f(4-1)+f(4-2)=f(3)+f(2)=1+1=2
so u have now the first 4 elements
0,1,1,2
now find f(5)=f(4)+f(3) the same way as before
f(5)=2+1=3
so u have now the first 5 elements
0,1,1,2,3

Answer 2

So, it is B. I have one more question if you do not mind helping. @ikram002p

Answer 3

ok lets see

Answer 4

Find f(5) for this sequence:

f(1) = 2 and f(2) = 4, f(n) = f(1) + f(2) + f(n - 1), for n > 2.

f(5) = ______

Numerical Answers Expected!

Answer 5

f(3)=f(1)+f(2)+f(3-1)=2+4+f(2)=2+4+4=10
f(4)=f(1)+f(2)+f(4-1)=2+4+f(3)=2+4+10=18
f(5)=f(1)+f(2)+f(5-1)=2+4+f(4)=2+4+18=24

Answer 6

okay so do I put all of that for f(5)=..................... ?

Answer 7

now what does "Numerical Answers" mean ?!

Answer 8

ok I know it now.
