A student is using the given data in the problem statement to find an approximate solution (accurate to 0.1) for the equation $\lg x = 2 - x$. He sets $f(x) = \lg x + x - 2$, finds that $f(1) < 0$ and $f(2) > 0$, and uses the "bisection method" to obtain 4 values of $x$, calculates the sign of their function values, and concludes that the approximate solution of the equation is $x \approx 1.8$. Among the 4 values he obtained, what is the second value?
