This is a linear sequence which we can see increasing by 4b with every consecutive term.

Given the values of the first 3 terms, we can see that the 4th and 5th terms must be a + 14b and a + 18b...

First of all we need to find the coordinates of the point D. As D is halfway between the two points A and B, to find the midpoint of a line segment, we add the x coordinates then divide by 2, and add the ...

1kg = 1000grams 5kg = 5000 grams. 5kg will give 20 bags (5000/250). Total amount she will make from selling is £13. Hence, profit percentage is (13-10)/10*100. Which gives profit percentage since profit i...
