Using product rule;
Let set A contains 3 elements
Set B contains 5 elements
First element of set A has 5 possibility, 2nd element of set A has 4 possibility and 3rd elements element of set A has 3 possibility for one one function.
Therefore total one to o

Find the generating function for sequences 4,4,4,4,..
- 1/(1-x)
- 1/(1+x)
- 4/(1-x)
- 4/(1+x)
- option3
Clear All
We know 1/(1-x)=1+x+x^2+x^3x+...
4/(1-x)= 4+4x+4x^2+...
Therefore sequence generated by 4/(1-x) is 4,4,4..
