Answer

\(\boxed{14.25}\)

Steps

Step 1 ：Given: $m=3, t=m-1$ and $n=t+5$

Step 2 ：Find the value of t: $t = m - 1 = 3 - 1 = 2$

Step 3 ：Find the value of n: $n = t + 5 = 2 + 5 = 7$

Step 4 ：Substitute the values of m, n, and t into the expression: $m+n^{2} / 2 t-1 = 3 + 7^{2} / 2(2) - 1$

Step 5 ：Calculate the result: $3 + 49 / 4 - 1 = 3 + 12.25 - 1 = 14.25$

Step 6 ：\(\boxed{14.25}\)
