Analysing the above series, we came across that the series has two parts.
Take the alternating numbers and make series as below:
100, 125, 150, 175, …. And 1000, 729, 512, ….
We need to find the next number in the second series. i.e. 1000, 729, 512, ….
We can write it as :
10^3, 9^3, 8^3, …
Therefore, the next number will be 7^3=343.
