Hey

henrymba2021It has been given that the first and second terms of the sequence are -3 and 2

Third term(odd term) can be got by adding 1 to the previous term, which is 2+1 = 3

Fourth term(even) can be got by multiplying -1 to the previous term, which is -3

Fifth term = -2, Sixth term = 2, Seventh term is 3, Eight term is -3

If you observe there is a pattern where the odd and even terms cancel each other.

The 147th term will be 3.

The sum of the 147 terms will be -3 + 2 + 0 + 0 + .... + 3 =

2(Option E)
