Common Mistakes to Avoid
✗ Forgetting to check your answer
✓ Always substitute n=1, 2, 3 to verify
One mistake can give a wrong formula
✗ Getting the sign wrong for d
✓ Decreasing = negative d
Check: does sequence go up (+d) or down (−d)?

✓ n is the position, the answer is the value
"5th term" means n=5, not the term = 5
