Question

in an ap an =2n+1 then find the common differences​

Answer 1

$\huge{\boxed {\mathfrak \pink {\fcolorbox {red}{blue}{AnSwEr}}}}$

an = 2n + 1

a1 = 2(1) + 1 = 2+1 = 3

a2 = 2(2) + 1 = 4+1 = 5

d = a2 - a1 = 5-3 = 2

Common difference = 2

Answer 2

A(n) means nth term; which for odd no.(2n+1); therefore common difference is 2;
Or if A(n) is 2n, an even no.,then also c.d is 2//
