    The Euler method is given by the formula:

    y_(n+1) = y_n + h*f(x_n, y_n)

    where y_n is the value of y at the nth step, x_n is the value of x at the nth step, h is the step size, and f(x_n, y_n) is the value of the derivative dy/dx at the nth step.

    In this case, the step size h = 0.4 since we are going from x = 1 to x = 1.4 in steps of 0.4.

    Using the given initial condition y = 3 at x = 1, we can start the iteration:

    x_0 = 1
    y_0 = 3

    At each step, we need to compute the value of the derivative dy/dx at the current step (x_n, y_n). In this case, dy/dx = 4(x - 2) - y.

    Step 1: (x_1, y_1)
    x_1 = x_0 + h = 1 + 0.4 = 1.4
    y_1 = y_0 + h*dy/dx = 3 + 0.4*(4(1) - 2) - 3 = 3 + 0.4*(4 - 2) - 3 = 3 + 0.4*2 - 3 = 3 + 0.8 - 3 = 0.8

    Therefore, at x = 1.4, y = 0.8.

    For finding y2, two iteration has to be followed. 
    dy/dx = 4(x + 2) - y  (given differential equation)
    y1 = y0 + hf(x0, y0)
    = 3 + 0.2 f(1, 3)
    = 3 + 0.2 [4(1 + 2) - 3]
    = 3 + 0.2 (12 - 3)
    = 4.8
    y2 = y1 + hf{x1, y1)
    = 4.8 + 0.2 f( 12, 4.8)
    = 4.8 + 0.2 [4(1.2 + 2) - 4.8]
    = 4.8 + 0.2 (12.8 - 4.8)
    = 4.8 + 1.6 = 6.4
