Below is code that will perform the task you have specified:

+++++++++++++++++++++++++++++

PROGRAM Successive_Sum;

Uses Crt;

Var sum, value, tmp : INTEGER;
avg : SINGLE;


BEGIN
ClrScr;
Writeln('Program to find the sum of 0, 1, 2, 3, ...');
Writeln;
Write('Enter stop value ');
Readln(value);
Writeln;

sum := 0;
For tmp := 0 to value Do
sum := sum + tmp;

Writeln('The sum from 0 to ', value, ' is ', sum);
avg := sum/value;
Writeln('The mean average is ', avg:3:2);
Writeln;
Writeln('Press RETURN to end this program');
Readln();
END.
