-12 + 2a = -6 (1+a)?
Answer is 0 = 6
Answer:
-2
Explanation:
The common difference of a sequence is the difference between consecutive terms. To find it, we subtract two consecutive terms.
1, -1, -3
1 and -1 are consecutive terms.
-1-1=-2
Therefore, the common difference is -2.
We can also try the same thing with -3 and -1, since they are also consecutive terms.
-3-(-1)
=-3+1
=-2
I hope this helps! Please comment if you have any questions.
1/2 * 1 * (1 + 1) = 1
1/2 * 2 * (2 + 1) = 3
1/2 * 3 * (3 + 1) = 6
1/2 * 4 * (4 + 1) = 10
Best answer me please!
