Answer:

$:\implies\tt (n + 1)/(2) = -(3)/(4) \\ \\ \\$

⚽ Cross multiplying both the sides we get :

$:\implies\tt (n + 1) * 4= -3 * 2 \\ \\ \\$

$:\implies\tt 4n + 4= -6 \\ \\ \\$

$:\implies\tt 4n = -6 - 4 \\ \\ \\$

$:\implies\tt 4n = -10 \\ \\ \\$

$:\implies\tt n = (-10)/(4)\\ \\ \\$

$:\implies\tt n = (-5)/(2)\\ \\ \\$

$:\implies \ddag \: \gray{ \underline{ \boxed{\tt n = - 2.5}}} \: \ddag\\ \\ \\$
