Question

the arithmetic sequence x , x , -3 , 2x what is the value of x

Answer 1

Answer:

x, x, -3, 2x cannot be an arithmetic sequence

Step-by-step explanation:

an arithmetic sequence has a constant difference between subsequent elements. That means

x - x = -3 - x = 2x - (-3)

0 = -3 - x = 2x + 3

and we get:

x = -3    ;     from 0 = -3 - x

and

x = -3/2    ; from 0 = 2x + 3

so there is no solution.
