It (2a) is the "width" of the given integral. Looking at the average integrand, I'd try a starting value of about 1 or 2.

So if the starting value isn't given should I just take value between 1 and 2

That range is based on what the function represents. In this case:
* Sketch the integrand from -3 to 3 say
* What interval [-a,a] would the area under the curve be approximately 100?,

Alternatively, guesstimate a value from the iteration formula. ln() must be positive, so a cannot be too large.

You can't just assume it's 1 or 2 for an arbitrary function.
