Directions: Look carefully for the pattern, and then choose which pair of numbers comes next.
Justification:
The relationship is x : x^3/2.
Directions: Look carefully for the pattern, and then choose which pair of numbers comes next.
Justification:
The relationship is x : (x^3 - x^2).
Directions: Look carefully for the pattern, and then choose which pair of numbers comes next.
Justification:
The relationship is x : (3x + 3).
Directions: Look carefully for the pattern, and then choose which pair of numbers comes next.
Justification: Number -> Sum of digits -> new sum of digits
363 -> 3 + 6 + 3 = 12 -> 1 + 2 = 3
489 -> 4 + 8 + 9 = 21 -> 2 + 1 = 3
579 -> 5 + 7 + 9 = 21 -> 2 + 1 = 3
471 -> 4 + 7 + 1 = 12 -> 1 + 2 = 3
