    ans can be calculated as: 1272 + 1272 + d(n/2)

    where d= difference between the consecutive terms i.e given constant
    and n= no. of terms i.e. given 46

    SOLUTION NO-1 =46/2(P1+P46)
    =23(P1+P46)

    SOLUTION NO-2 =46/2{ 2(P1)+(46-1)(CONSTANT DIFFERENCE TERM)}
    23 { 2(P1) + (46-1)(CD) }
    where CD is CONSTANT DIFFERENCE TERM
