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:

$1$
