Each term is multiplied by 2. 80 × 2 = 160
This is the Fibonacci sequence where each term is the sum of the previous two terms. 13 + 21 = 34
Squares of consecutive integers: 11², 12², 13², 14², 15², 16² = 256
Perfect squares: 1², 2², 3², 4², 5², 6², 7², 8² = 64
Each term is multiplied by 2: 11 × 2 = 22, 22 × 2 = 44... 176 × 2 = 352
Fibonacci sequence where each term is sum of previous two: 21 + 34 = 55
Squares in descending order: 12², 11², 10², 9², 8², 7² = 49
Pattern: n² + 1 for n = 1, 2, 3... gives 2, 5, 10, 17, 26, 37, 50
Differences increase by 1 each time: +1, +2, +3, +4, +5, +6. So 20 + 6 = 26
Each term is the factorial of its position: 1!, 2!, 3!, 4!, 5!, 6! = 720
