    \purple{\bf {\underline {Given:-}}}

    In an A.P

    ▪a = 10

    ▪n = 6

     a_{n} = 10

    \pink{\bf {\underline{To\:Find:-}}}

    ▪The value of d

    \huge\orange{\bf{\underline {Solution:-}}}

    We know that,

     \red{ \star\bold{ \: a_{n} = a + (n - 1)d}}

    ⇒10  = 10 + (6 - 1)d

    ⇒10 = 10 + 5d

    ⇒10  - 10 = 5d

    ⇒5d = 0

    ⇒d =  \frac{0}{5}

    ⇒d = 0

    \bold\green {Hence,\: the\: value\: of \:d \:is \:0}
