If there is a constant value being added "2, 4, 6.... (2 is added)" then "a+d(n-1)" is used!
but is subtracted then"a-d(n-1)"

Yes but if it is like 1,2,4,7,11 so that the difference between 1 and 2 is 1 and between 2 and 4 is 2 then 3 then 4 then 5 and so on...
What formula should I use?

firstly kik the calculator pick the pencil and do step by step working u willlnever go rong
next wen do this the other qustions are also ez
c i
gives u equation which equals to zero nad that equation is y
as stated in the first part of the question
so y=zero which simply means x ais see where ur hgraph and x axis meet
in part ii im not sure
in part d i u have alreday drew one part of the equation so draw the other part of the equation which is linear that is it will be a sraight line
where they meet -=answer
d part ii DO THE ALGEBRA and compare the quadratic equation u got with the ne they gave a nd see which letter = which number!
