Question

write common difference of this A.P
->0.7.0.15,0.23.....​

Answer 1

Answer:

Type u question properly my buddy…

It is 0.7, 0.15, 0.23

Step-by-step explanation:

Here's your answer

Common difference (d) = $A_{2}$ - $A_{1}$

                                       = 0.15 - 0.7

                                       = 0.8

Hence, d is 0.8

Hope it Helps U

If so mark me Brainliest :P

Answer 2

Given :

• AP : 0.7 , 0.15 , 0.23 ....

To find :

• Common difference (d)

Solution :

The common difference of an AP is given by :

Common difference = Second term - first term

d = 0.15 - 0.7

d = 0.8

Let us check if our common difference is correct :

Second term - first term = Third term - second term

0.8 = 0.23 - 0.15

0.8 = 0.8

LHS = RHS

Hence , common difference = 0.8

AP stands for arithmetic progression . In this series each consecutive term differs by a common difference . The general equation for an AP is given by :

• AP : a , a + d , a + 2d , a + 3d ......

Some of the terms of AP are :

• Common difference : This is the difference between each term in an AP .
• First term : This is the first term of AP denoted by a .
• nth term : This is the nth term of AP and is given by the formula $\rm a_n = a + (n-1)d$ .

Sum of the AP :

The formula of sum of n terms of an AP with common difference d is :

$\rm S_n = \dfrac{n}{2} [2a + (n - 1) d]$
