Question

the nth term of an A. P is( 2n-3) find the common different. ​

Answer 1

$<i>Heya! </i>$
___________________________________________________

$<b><u> Arithmetic Progressions:- </b></u>$

→ Nth term = 2n - 3

◾Put n = 1

=> 2 ( 1 ) - 3

=> -1 ✔

◾Put n = 2

=> 2 (2) - 3

=> 1 ✔

◾Put n = 3

=> 2 (3) - 3

=> 3

•°• The A.P becomes → -1 , 1 , 3.......

Here ,

$<b> ▪First term a = -1 </b>$

$<b> ▪Common Difference d = 1 - (-1) = 2 </b>$

$Thanks!!$

Answer 2

2n - 3

= -1 , 1 , 3 is the Ap by n = 1,2,3

Common difference d = 2
