$\sf\huge\blue{\underline{\underline{ Question : }}}$

The nth term of a sequence is 2n - 3,find it's fifteenth term..?

$\sf\huge\blue{\underline{\underline{ Solution : }}}$

★ Given that,

• nth term of an AP series : 2n - 3.

★ To find,

• 15 th term.

★ Let,

To find the value of 15th term substitute n = 15.

⇒ a15 = 2(15) - 3

⇒ a15 = 30 - 3

⇒ a15 = 27

# Hence, value of the term 15 is “ 27 ”.

★ More Information :

$\boxed{\begin{minipage}{5 cm} AP Formulae \\ \\ : \implies a_{n} = a + (n - 1)d \\ \\ :\implies S_{n} = \frac{n}{2} [ 2a + (n - 1)d ] \end{minipage}}$
