Answer:
Step-by-step explanation:
These are geometric means problems. In the top one, a is the geometric mean as the height for both the smaller triangles inside the big one. Therefore,

The next one has the geometric mean of b, being a part of the smaller triangle on the left and the big triangle as a whole:

Answer:
=
+ 6
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
- 11 - (- 17) = - 5 - (- 11) = 1 - (- 5) = 6
A recursive rule allows a term to be found by adding d to the previous term, thus
=
+ 6 with a₁ = - 17
