1440
The series follows a multiplication pattern with increasing factors: ×6, ×5, ×4, ×3, ×2.
The series follows a multiplication pattern with increasing factors: ×6, ×5, ×4, ×3, ×2.
Analyze the pattern
Calculate the ratio between consecutive numbers: 24/4 = 6, 120/24 = 5, 480/120 = 4.
Predict the next term
Following the decreasing multiplier pattern (6, 5, 4, 3...), multiply 480 by 3.
Verification
480 × 3 = 1440. To verify, 1440 × 2 = 2880, which matches the final term of the series.
B: 1080 is incorrect as it results from multiplying by 2.25, not 3; C: 1220 and D: 1360 do not satisfy the mathematical multiplication sequence.
A is correct because the series follows a pattern of multiplying each term by a decreasing factor starting from 6: (×6, ×5, ×4, ×3, ×2).
If the differences between terms are large, always check for multiplication or squares/cubes before checking addition/subtraction series.
