I need help i can’t understand how to solve it so pls help

=====================================================

Work Shown:

The first four terms are: -4, 14, -22, 50

The idea is to start with the first term (-4) and use the template to generate each new term. We multiply the previous term by -2, then add on 6. This is exactly what the recursive equation is indicating.

for ex: the reciprocal of 3/4 is 4/3. it is the opposite.

reciprocal definition:

a mathematical expression or function so related to another that their product is one; the quantity obtained by dividing the number one by a given quantity.
