The correct option is E 250
In this example two series are combined together
First consider the terms only at the odd positions and find out the pattern
2 4 12 48 250
2×2=4.
4×3=12.
12×4=48.
48×5=240250.
Now consider the terms at the even position and find the pattern
3 6 12 24
3×2=6.
6×2=12.
12×2=24.
All the terms follow the same pattern So, 250 is the wrong term
