I agree, the answer is: -2

The formula for the nth term is given as follows:

It's alternating between + and -

first, third and fifth step are + (1, 3 and 5 respectively)
second, fourth and sixth step are - (2, 4 and 6 respectively)

So 4-6= -2!

im going -2. looks like +1 -2 +3 -4 +5 -6 to me

Thanks for running these competitions, its great to be a winner of something for once! Here is my go at this weeks quiz

I think the answer is -2
The change from the previous number is +1 , - 2 , +3 , -4 , +5 , -6
In equation form Xn = X(n-1) + (-1)^n* (n-1)
So the seventh number X7 = 4 + -1 * 6 = -2

yep, clearly -2 is the next in the sequence

Subtracting the number from the previous number gives me 1,-2,3,-4,5 so the next difference should be -6.

Therefore the next number in the sequence is -2
