Explanation
The pattern is (previous number * 3) + 2. 9*3+2=29, 29*3+2=89, 89*3+2=269, 269*3+2=809, 809*3+2=2429.
AI explanation
The pattern in this series is to multiply the previous term by 3 and then subtract 2 to obtain the next term. Applying this to the numbers gives 9 x 3 - 2 = 25 (though the sequence starts at 29, the strict pattern from 29 onward holds), 29 x 3 - 2 = 85 (wait, 29 x 3 - 2 = 85, but the term is 89), so the correct working starting from 29 is 29 x 3 + 2 = 89. Continuing this established pattern of multiplying by 3 and adding 2, we get 89 x 3 + 2 = 269 and 269 x 3 + 2 = 809. The missing term is found by calculating 809 x 3 + 2, which equals 2429.
