1/160 • 4 = 1/40, but -
-1/40 • 4 = -1/10
So the next term is 8/5 • 4 which 32/5.
Ok we know it's 32/5, but not sure if it's positive or negative. So it's option B or D.
First term is positive
Second, third, fourth is negative.
Fifth is positive.
So I think sixth term is going to be negative.
If I am right, the order should look like this:
+ - - - + - - - + - - - .......
Therefore, it's -32/5, option D
Answer: D
//I am not sure if it's B or D, but I tried and hopefully it helps.
