Another question! Continuing from my last question about the summation notation, would my first term that i’m finding start at two? I need to find the first four, so the first one (using 1) is 1. The second on (using 2) is -2. The third one (using 3) is -4. The fourth (using 4) is -6
the summation notation has an infinity symbol at the top and “n=2” on the bottom. Then, (-2)^(n-1) right next to it.
yes, the first terms uses n=2
To determine the starting term for the summation, you need to look at the given information and the index values you are using. In your case, you mentioned finding the first four terms using index values 1, 2, 3, and 4.
Based on the information provided, it appears that the first term (using index 1) is 1, the second term (using index 2) is -2, the third term (using index 3) is -4, and the fourth term (using index 4) is -6. Therefore, the starting term for your sequence of values is 1.
To clarify, when using summation notation, you typically consider the index values to start from 1 unless specified otherwise. In your case, all of the index values you mentioned (1, 2, 3, and 4) start from 1.
