I believe it's the top right one.
Answer:
,-3
Step-by-step explanation:
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.
A to D - 2 letters in between
D to I - 4 letters in between
I to P - 6 letters in between
P to Y - 8 letters in between
the answer should be Y.
hope this helps :)
Yes, if you do it correctly by following the Algebraic way you would get:
x-4=5
you need to find x.
you can do this by subtracting 4 from the x side and adding it to 5.
so it would be x= 5+4
then you jsut add 5 and 4 and you get x.
so x = 9.
