Answer:
The 9th term of the series is 256
Step-by-step explanation:
Here we have the numbers as follows
1, 2, 4 from we have;
1 = The first term of the series
2 = The second term of the series
4 = The third term of the series
From the definition of the series, the sum of the factors is 1 less than twice the number, therefore, since 4 satisfies all the conditions, we observe that;
4×2×1 = 8 also satisfies all the conditions, hence we have;
8 = The fourth term of the series
8 × 2 = 16 = The fifth term of the series
16 × 2 = 32 = The sixth term of the series
32 × 2 = 64 = The seventh term of the series
64 × 2 = 128 = The eight term of the series
Therefore, the 9th term of the series = 128 × 2 = 256.
