Question

Write a program to display the following series of numbers 7 14 21 ... 70

Answer 1

Explanation:

14 - 7 = 7

21 - 14 = 7

Thus numbers are in A.P. whose 1st term is a and common difference is d.

For this problem. a = 7 and d = 7

It's rth term will be

a + (r-1 )d = 7 + ( r -1) 7 = 7r

Answer 2

Explanation:

C++ is one of the basic computer programming language. A program fulfilling the requirements of the mathematical expression can be written as;

Int main ( int x, int y)

{

int z = 7;

int o;

for (int i = 1; i <= 10; i++)

{

o = z * x;

       print("Value of Series is o: %z)

}

Return z

}
