Balance Scale Equation

The animation visualizes solving the equation 150 = 7 + 4(n − 1) using a balance scale, demonstrating that performing the same operations (subtracting 7, dividing by 4, and adding 1) to both sides keeps the scale level. It concludes by showing that the resulting value, n = 36.75, is not a whole number, proving that 150 is not a term in the sequence.
