Given the following question:
First expression:
Second expression:
If you notice the terms, they're
7, -21, 63, -189 and so forth.
7*-3 = -21 and -21 * -3 is 63 and so forth, meaning the "common ratio" is -3.
now, for a common ratio say "r", which is a fraction, namely less than ±1 and more than 0, or |r| < 1 , you do have a convergent sequence.
however this one notice, |-3| is 3, and that's greater than 1 clearly, therefore is divergent, meaning the summation has no finite value.
The nucleus contains the genetic material of an eukaryotic cell.
Y+3=0 is vertical line -3 on the graph.
Hope this helps there was no choices.
