mathematical operations
Sequences are formed by applying a mathematical operation to each number (either addition, subtraction, multiplication or division)
1, 3, 5, 7, 9 (add 2 to each number)
50, 45, 40, 35 (subtract 5 from each number)
2, 4, 8, 16, 32 (multiply by 2)
1000, 100, 10 (divide by 10)
1, 3, 5, 7, 9 (add 2 to each number)
50, 45, 40, 35 (subtract 5 from each number)
2, 4, 8, 16, 32 (multiply by 2)
1000, 100, 10 (divide by 10)
special types of numbers
|
Some sequences are formed based on special TYPES OF NUMBERS that are formed in a special way. These include Square Numbers, Triangular Numbers, Prime Numbers, Cubed Numbers.
1, 3, 6, 10 (triangular numbers) (1, 1+2, 1+2+3, 1+2+3+4) 1, 4, 9, 16, 25 (square numbers) (1x1, 2x2, 3x3, 4x4,5x5) 2, 3, 5, 7, 11 (prime numbers) 1, 8, 27, 64 (cubed numbers) (1x1x1, 2x2x2, 3x3x3, 4x4x4) |
