Answer 2

Question:

Write a program in QBASIC to display the following series.

0 7 26 63.....N terms.

Program:

This is an easy question. Read this post to get your answer.

Here is the program.

CLS

INPUT "ENTER THE NUMBER OF TERMS - "; N

PRINT "Here is your series....."

FOR I = 1 TO N STEP 1

PRINT (I^3 - 1) + " "

NEXT I

PRINT "Program finished..."

END

Logic:

0 = 1³ - 1

7 = 2³ - 1

26 = 3³ - 1

Hence, nth term of the series is n³ - 1

In this program, we have created a loop and then calculated each term of the series and it is displayed.

Syntax of for loop:

FOR <VARIABLE> = <INITIAL_VALUE> TO <FINAL_VALUE> STEP <STEP_VALUE>

statements

.

.

NEXT <VARIABLE>

In this program, I is the variable, initial value is 1 and the final value is n. Step value is 1.
