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

If a25 - a17 = 32,then d = ?

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

★ Given that,

• a25 - a17 = 32

★ To find,

• Value of d. (Common difference)

★ Let,

• a25 = a + 24d
• a17 = a + 16d

• Substitute the values.

$\bf\:\implies a + 24d - (a + 16d) = 32$

$\bf\:\implies a + 24d - a - 16d = 32$

$\bf\:\implies 8d = 32$

$\bf\:\implies d = \frac{32}{8}$

$\bf\:\implies d = 4$

$\underline{\boxed{\bf{\purple{ \therefore d = 4}}}}\:\orange{\bigstar}$
