Option 1: –5160
Option 2: –6075
Option 3: –7250
Option 4: –8400
Correct Answer: –6075
Solution :
Given:
25, –75, 225, –675, 2025, ?
Multiply the previous term by (–3), to obtain the next term in the series –
25 × (–3) = –75; –75 × (–3) = 225; 225 × (–3) = –675; –675 × (–3) = 2025; 2025 × (–3) = –6075
So, –6075 is the missing term in the given series. Hence, the second option is correct.
