Question

n-(n-1)/2=1-(n-2)/3​

Answer 1

Answer is one hope this is the brainless

Answer 2

Answer:

$n-\frac{n-1}{2} =1 - \frac{n-2}{3}$

cross multiplying we get,

$\frac{2n-n+1}{2}=\frac{3-n+2}{3}$

cross multiplying we get,

6n-3n+3=6-2n+4

3n+2n=10-3

5n=7

n=  $\frac{7}{5}$

therefore n=7/5
