There is no series of number: just one very large number!
A series is a set of partial sums of sequences of numbers. A single number, such as 135, does cannot define a series.
17
10,11,13,14,15,17
17 cause it is the next prime number
It is: 1000 because they are all consecutive cubed numbers
The given series appears to be a sequence of numbers that increases by adding 1 to the previous number while maintaining the same digits. Following this pattern, the next number after 7218729 would be 7218730.
The pattern is add three and then multiply by three. The next number is 174.
the numbers are only dividable by 1 or themselves, the so called, 'prime numbers', so the next one would be 17.
10 the sequence is 3 numbers miss one, three numbers miss one, etc
One number does not make a sequence (nor a series).
Answer = 21 The next number is the previous 2 numbers added together
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.
