 Given \: sequence\: m-2n, m-n, m ,\cdot\cdot\cdot

 First \:term (a) = m - 2n

 a_{2} - a_{1}\\ = m - n - ( m - 2n ) \\= m - n - m + 2n \\= n

 a_{3} - a_{2}\\= m - ( m - n ) \\= m - m + n \\= n

 a_{2} - a_{1} = a_{3} - a_{2} = n

 \therefore The \: sequence \:is \: in \:A.P

 Common \: differnce (d) = n

 \boxed{ \pink { n^{th} \: term (a_{n}) = a + (n-1)d }}

 Here, a = m - 2n, d = n \: and \: n = 11

 \red{ 11^{th} \:term } \\= a_{11} \\= (m-2n) + ( 11 - 1 )n \\= m - 2n + 10n \\= m - 8n

Therefore.

 \red{ Required \: 11^{th} \:term } \green {= m - 8n}
