Directions: Look carefully for the pattern, and then choose which pair of numbers comes next.
Justification: The relationship is x^3 : (x + 1)^3 + 1.
Directions: Look carefully for the pattern, and then choose which pair of numbers comes next.
Justification: Sum of digits of the first number is 2 more than the sum of digits of the second number.
Directions: Look carefully for the pattern, and then choose which pair of numbers comes next.
Justification: The relationship is x : x(x + 1).
Directions: Look carefully for the pattern, and then choose which pair of numbers comes next.
Justification:
The relationship is x^2 : (x -1)^(2+1)
So, required number (4 – 1)^(2+1)=27.
Directions: Look carefully for the pattern, and then choose which pair of numbers comes next.
Justification:
The relationship is x^p : (x + 1)^(p+1).
So, required number (4 + 1)^(3+1) = 5^4 = 625.
