90%	Find Sₙ of a given AP (direct or 'sum of multiples of k') — Find a, d, and n (via the last term). Pick the correct Sₙ formula. Simplify the bracket fully before multiplying.	3 MARKS
80%	Which term equals X / is X a term of the AP — Set aₙ = X, solve for n using a + (n−1)d. Validate n is a positive integer; else 'not a term'.	2 MARKS
70%	Find a and d (or a missing term) from two conditions — Write two equations from the two given terms/sums; solve the simultaneous pair for a and d.	3 MARKS
65%	Word/case-study: savings, salary, seats, logs, installments forming an AP — Translate the story into a, d, n; identify whether an or Sₙ is asked; answer in the question's units.	4 MARKS
55%	Find the middle term / first negative term of an AP — Middle term: locate term number (n+1)/2 (odd count). First negative: solve a + (n−1)d < 0 for smallest integer n.	3 MARKS
