Tips:

• Check the differences between consecutive numbers first — a constant difference means simple addition.
• If differences aren't constant, try ratios next — the sequence might be multiplying each time.
• Watch for perfect squares (1, 4, 9, 16, 25…) and Fibonacci-style sums (each number equals the sum of the two before it) — both are common patterns here.
• If nothing fits, look for an alternating pattern — add, then subtract, repeating.
