The pattern suggests that each letter represents its position in the alphabet (A=1, B=2, C=3, D=4).
So, AB = 1+2 = 3 (concatenated to 12), BC = 2+3 = 5 (concatenated to 23), and CD = 3+4 = 7 (concatenated to 35).
The sequence increases by 4, 6, 8, ..Therefore, the next increase should be 10. Adding 10 to the last number (20) gives 30.
Since all squares are rectangles and all rectangles are shapes, it follows that all squares are shapes.
The plane travels at a speed of 500 miles per hour. Therefore, it will take 3 hours to travel 1500 miles (1500 / 500 = 3).
Carrot is a vegetable, while the other three are fruits.
Each number in the series is multiplied by 3. Therefore, 135 multiplied by 3 equals 405.
All other options are sequences that follow a consistent multiplication pattern (2x, 3x, 5x), whereas 7, 14, 22 does not follow a consistent pattern.
