Question

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) = ______

Answer 1

\[f(n)=f(1)+f(2)+f(n-1)\]
now here put
\(n\)=3
u'll get value of f(3)

Answer 2

after that put n=4

Answer 3

f(3)=f(1)+f(2)+f(n-1)=2+4+2=8

Answer 4

2+4+3=9

Answer 5

what is that?

Answer 6

f(4)=f(1)+f(2)+f(4-1)=2+4+3=9

Answer 7

how come f(3)=8

Answer 8

it will be 10

Answer 9

^*sorry

Answer 10

yup i meant f(4-1)=f(3)=8

Answer 11

how

Answer 12

ok??

Answer 13

ok thanks now i got it so the answer of f(5)=22

Answer 14

yup well done :)

Answer 15

:)

Answer 16

can you help me with another question please

Answer 17

yeah u can ask it separately closing this one :)

Answer 18
