Question

find the nth term of the 5,10,15,20,25....

Answer 1

Answer:

Step-by-step explanation:

An= A+(n-1)d

A=5

D=5

An=5+(n-1)5

=5+5n-5

=5n

An=5n

Answer 2

The nth term of the 5 , 10 , 15 , 20 , 25 , . . . is 5n

Given :

The progression 5 , 10 , 15 , 20 , 25 , . . .

To find :

The nth term

Concept :

If in an arithmetic progression

First term = a

Common difference = d

Then nth term of the AP

= a + ( n - 1 )d

Solution :

Step 1 of 3 :

Write down the given progression

The given progression is

5 , 10 , 15 , 20 , 25 , . . .

This is an arithmetic progression

Step 2 of 3 :

Write down first term and common difference

The arithmetic progression is

5 , 10 , 15 , 20 , 25 , . . .

First term = a = 5

Common Difference = d = 10 - 5 = 5

Step 3 of 3 :

Find the nth term

Then nth term

= a + ( n - 1 )d

= 5 + ( n - 1 ) × 5

= 5 + 5n - 5

= 5n
