Determine if the following sequence is geometric
a) 5,2,-1,-4

b) 5,10,20,40

A) No. It is an arithmetic sequence because you are subtracting by 3.

B) Yes. It is a geometric sequence because you are multiplying by 2.

Step-by-step explanation:

Arithmetic is addition or subtraction.

5 - 3 = 2    2 - 3 = -1    -1 - 3 = -4

Geometric is multiplication.

5 X 2 = 10    10 X 2 = 20    20 X 2 = 40

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol
