He needs 6 litres of the 20% and 2 litres of the 60% a simple trial and error method will do in this type of equation
If a = 4 and d = 3,

Answer: The general equation for the nth term is 3n + 1.---------------------------------------------------------------------------------------
We can assume that this growth rate can be expressed as y = mx + b as long as the slope is constant, because a quadratic or exponential formula wouldn't make much sense in this situation. If it is growing at least 2 inches a month, the slope (m) will be 2. As x (month) increases by 1 month, y (plant's height) increases by 2 inches. You could make it more, but as long as you plot the points in such a way that the slope for these points are 2 or higher, you will get the answer correct. If you have any other questions or need to clarify more about what you wanted let me know and I'll help.
it won't let me type the answer I may be missing something but it says I am using rude words so sorry if I am
