Which number comes next in this seriesWhich number comes next in this series 18 81 27 72 36 63?

The series alternates between two patterns: one where numbers are multiplied by 3 and then reduced (18 to 27 to 36) and another where numbers are multiplied by 4 and then reduced (81 to 72 to 63). Following this pattern, the next number after 36 (from the first sequence) would be 45 (36 multiplied by 1.25), and after 63 (from the second sequence), the next number would be 54 (63 reduced by 9). Thus, the next number in the series is 45.


What is the next number in the series 14 -11 18 -16 13 -17 18?

To find the next number in the series, we can observe the alternating pattern between pairs of numbers. The first number is 14, and it decreases by 3 to 11, then increases by 7 to 18. Following this pattern, the next number after 18 should decrease by 2, resulting in 16. Therefore, the next number in the series is 16.


What number comes next in the series 3-6-18-72?

Each number in the series is being multiplied by (2 + (n-1)) where n = the term in the series 3 x 2 = 6 6 x 3 = 18 18 * 4 = 72 72 x 5 = 360


What number comes next in the series 77 49 36 18 9?

It appears as if you are multiplying the digits together to create the next number. If that's true, the fifth number would be 8 and the sixth digit and any after that would be zero.


Which number comes next in this series 15-18-54-57-171?

The pattern in the series appears to alternate between adding 3 and multiplying by 3. Starting with 15, we add 3 to get 18, then multiply by 3 to get 54. Next, we add 3 to 54 to get 57, and then multiply by 3 to reach 171. Following this pattern, the next step is to add 3 to 171, which gives us 174. Thus, the next number in the series is 174.
