Answer:
- 8
Step-by-step explanation:
The common difference d between consecutive terms is
d =
-
, that is
d = - 4 - (- 2) = - 4 + 2 = - 2
To obtain the next term subtract - 2 from - 6
next term = - 6 - 2 = - 8
They are supplementary angles because their sum equals 180 degrees, and they are adjacent because they share a side.
This equation can be used when comparing ages.
An example to illustrate this:
Assume that adding 6 to 3 times the age of Jack will give us the age of his grandfather.
When translating this into equations, assuming that the age of jack is "a" and the age of his grandfather is "b", we will find that:
b = 6 + 3a
Take the root of both sides and solve.
c = - 7 sqr root 5
c = -1.258
