Answer
Explanation:
Step1: Calculate $\Delta x$ formula
The formula for $\Delta x$ in a Riemann - sum on the interval $[a,b]$ with $n$ sub - intervals is $\Delta x=\frac{b - a}{n}$. Here, $a = 2$, $b = 7$ and $n = 5$. $\Delta x=\frac{7 - 2}{5}$
Step2: Compute $\Delta x$ value
$\Delta x=\frac{5}{5}=1$
Answer:
$1$
