${\huge{\bold{\purple{\bigstar{\boxed{\bf{Answer}}}}}}}$

${\bold{\blue{\boxed{\bf{Given}}}}}$

• first term = a = 32
• common diff. = d = -4
• no. of times =n= 11

${\bold{\blue{\boxed{\bf{To\:find}}}}}$

• $\bold{a_{11}}= ???$

$\bold a_n = a + (n-1)d$

${\bold{\blue{\boxed{\bf{ Formulae\:used }}}}}$

$a_{11} = 32 + (11-1)\times - 4$

$a_{11} = 32 + 10 \times -4$

$a_{11} = 32 - 40$

$a_{11} = -8$
