D Correct answer
Explanation

The pattern is: 4*2=8, 8*2.5=20, 20*3=60, 60*3.5=210, 210*4=840, 840*4.5=3780. The term 1050 is incorrect as it should be 840.

AI explanation

The series follows the pattern of multiplying consecutive natural numbers, starting from 2. The correct sequence of multipliers is 2, 2.5, 3, 3.5, 4, 4.5. Multiplying 210 by 3.5 gives 735, and then multiplying 735 by 4 gives the correct next term of 2940. Since the series lists 1050 instead of 2940, it is the wrong term.
