    f(x)= -2x-3

    Step-by-step explanation:

    Step 1:

    Let the sequence given here is -5, -7, -9, -11, -13 ……

    Here the first term (a₁) of sequence is -5

    And the common difference between the numbers in the sequence is

    d= (-7-(-5)) = -7+5 = -2

    Let the number of terms be x

    Step 2;

    To find the sequence function basic arithmetic sequence formula is

    aₙ = a₁ + d( x-1)

    Applying the values we get

    f(X) = -5 + ((-2)(X-1))

    on simplification

    f(X) = -5 + (-2X+2)

    f(X)= -5+2-2X

    f(X)= -3-2X
