Question

find the comman difference of an A.P whose first term is 12 and fifth term is 0​

Answer 1

$\huge\mathfrak{Solution}$

Given;

In AP , a =12 and fifth term(a5)=0

So;

a5=a+4d

0=a+4d

0=12+4d

-12=4d

d=-12/4

$\small\boxed{d=-3}$

Answer 2

The common difference of an A.P is -3.

Step-by-step explanation:

Given : An A.P whose first term is 12 and fifth term is 0​.

To find : The common difference of an A.P ?

Solution :

The first term of an A.P is a=12

The fifth term of an A.P is $a_5=a+4d$

We have given, $a_5=0$

Substitute the value,

$0=12+4d$

$4d=-12$

$d=-\frac{12}{4}$

$d=-3$

The common difference of an A.P is -3.
