Chain Reaction – Level 1 – Medium

Home » Puzzles » Chain Reaction » Level 1 - Medium » Chain Reaction – Level 1 – Medium
Topics: answers, chain, questions, sequential reasoning

Each answer you find is used inside the next question. Work through the full chain carefully – if you get one wrong, it affects the rest!

Your Workings For Chain Reaction

1) Solve: 8x – 10 = 4x + 2

A =

2) Use your answer from Q1 as “a”. Now solve: 4a – x + -2 = 6

B =

3) Use your answer from Q2 as “b”. Now simplify: (x + 5)(x + b) – what is the coefficient of x?

C =

4) Use your answer from Q3 as “c”. Now solve: 2(x + 1) – c = -47

D =

5) Use your answer from Q4 as “d”. Now factorise: x² – dx + 36

E =

Chain Reaction – Medium

Medium puzzles usually include a mix of solving, simplifying, and extracting specific parts (like constants or coefficients). The chain still works the same: each answer becomes the next input.

Workflow:

  • Preview the chain and note where you’ll need to expand or factorise.
  • After substitution, simplify fully before solving (this prevents sign errors).
  • Keep a running list: a = …, b = …, c = … so you can spot mistakes quickly.

Tip: if a step asks for a coefficient/constant, you don’t need to “solve” — you need to simplify and read the requested part.
