first check is n=1 true statement or not ? substitute n for 1

3. anonymous

how do i do that

4. anonymous

sorry im really slow today i jsut got home from base

5. Nnesha

$n^2-n+2 =2$ substitute n for 1 do you get equal sides ?

6. anonymous

not really sorry

7. Nnesha

these are the steps for mathematical induction 1st) substitute n for 1 to check is the L.H.S = R.H.S ? if the statement is true then next step is 2nd) assume it is true for n=k (substitute n for k) this step is called " induction assumption' 3rd) substitute n for k+1 and we want to show the statement is true for n= k+1 based on the 2nd step assumption

ohh ok

9. Nnesha

what do you mean replace n with one and then solve left side both sides are equal at the end ?

10. anonymous

what?? im confused

11. anonymous

why did you ask that question for?

$$\color{blue}{\text{Originally Posted by}}$$ @Nnesha $n^2-n+2 =2$ substitute n for 1 do you get equal sides ? $$\color{blue}{\text{End of Quote}}$$ this is simple algebra substitute n for 1 then solve left side

14. Nnesha

if both sides are equal THEN we can work on 2nd step

15. anonymous

and how do we do that

16. anonymous

??

17. Nnesha
