Conclusion:  The solution derived using the modified Euler's method is in the form of a table of the variable function y(x), as shown in the second column of the table above. Since the global apriori error of the method is О("Euler_mod_EN_20.gif") and here h=0.1, then these solutions must be rounded to only two signs after the decimal point.
