<h3>
Answer: (n-1)^2</h3>
This is because we have a list of perfect squares 0,1,4,9,...
We use n-1 in place of n because we're shifting things one spot to the left, since we start at 0 instead of 1.
In other words, if the answer was n^2, then the first term would be 1^2 = 1, the second term would be 2^2 = 4, and so on. But again, we started with 0^2 = 0, so that's why we need the n-1 shift.
You can confirm this is the case by plugging n = 1 into (n-1)^2 and you should find the result is 0^2 = 0. Similarly, if you tried n = 2, you should get 1^2 = 1, and so on. It appears you already wrote the answer when you wrote "Mark Scheme".
All of this only applies to sequence A.
side note: n is some positive whole number.
Answer: x=1
Step-by-step explanation:
Hey there!
When you multiply across, you get the following product:
<span>
8 </span>× –<span>23 </span>× –<span>21 </span>× –<span>29
</span>–184 × –21 × –29
3864 × –29
–112,056
The sign will be negative.
Hope this helped you out! :-)<span />
Answer:
CBA = DEF
Step-by-step explanation:
DEF is the answer because CBA is the exact same triangle as the other one, it just upsidedown.
