Answer 2

$\huge{\orange{\bold{\underline{ \mathbb{ÀnsWeR:-}}}}}$

$\huge{\blue{\bold{\underline{\mathbf{given:-}}}}}$

Our A.P is 11,9,7,5....

$\huge{\blue{\bold{\underline{ \mathbf{to \: find:-}}}}} </p><p></p><p></p><h2>nth<em><u> </u></em><em><u>term</u></em> of this A.P??</h2><p></p><p>[tex]\huge{\blue{\bold{\underline{ \mathbf{solution:-}}}}}$

$a_{n} = a + (n - 1)d \\ \rightarrow \: 11 + (n - 1)( - 2) \\ \rightarrow \: 11 - 2n + 2 \\ \rightarrow \: \bold{{13 - 2n}}$

Hope it helps you.....✌✌
