The first step would be to put in the fact that the sequence starts at 8
y = 8 + _x
The blank is going to include the difference between each number in the sequence; that is, how much it’s increasing by. To find it, get the difference between any two (consecutive!) terms.
10 - 8
12 - 10
14 - 12
All of these are equal to 2. Therefore, our gap is going to include “2”
y = 8 + 2x
To find the hundredth term, simply plug in 99 for x (the reason being that plugging in 0 for x gives us 8, but this is considered the first term. Therefore, x - 1 is the actual term)
y = 8 + 2(99)
y = 8 + 198
y = 206
