Question

In the Arithmetic progression => 3, 1, -1, -3 what is the common difference for this AP ਦਿਤੀ ਹੋਈ AP ਵਿਚ ਸਾਂਝਾ ਅੰਤਰ ਕੀ ਹੈ ?3, 1, -1, -3 (1 Mark)

1

2

0

-2

​

Answer 1

Step-by-step explanation:

common difference=a2-a1=common difference of the AP

now,

heare a1=3and a2=1

so,a2-a1=1-3=. -2solution

Answer 2

$\huge\underline{\mathbb\red{✰Q}\green{u}\mathbb\blue{e}\purple{s}\mathbb\orange{ti}\pink{on}}\:$,

• A.P .. 3, 1 , -1 , - 3

to find, common difference

✰ solution

• the difference between any two consecutive terms in a.p is called the common difference.

$\huge\underline{\mathbb\red{➻A}\green{N}\mathbb\blue{S}\purple{W}\mathbb\orange{E}\pink{R}}\:$,

second term - first term

• 1 - 3 = - 2
• d = - 2
