They seem to be very descriptive and use lots of examples of nature.
<span>2y = 4x + 8 ------> y = 2x + 4
4y = 4x + 20 ------> y = x+5
2x+4 =x+5
x = 1
y=x+5=1+5=6
Check:
</span>2*6 = 4*1 + 8 , 12 =12
4*6 = 4*1 + 20, 24 =24<span>
x=1,y=6
(1,6)
</span>
Looking at the numbers, we can see that the differences are 72, 36, and 18. Notice that they are each factors of the next by the same constant 2.
18 * 2 = 36
36 * 2 = 72
There, it means that 18/2 will be subtracted from 20.
20 - 18/2
= 20 - 9
= 11
The next number in the sequence would be 11. Hope this helps!
