Answer:
x = 2
Step-by-step explanation:
5x + 3 = 7x - 1
Subtract 3 to both sides
5x = 7x - 4
Subtract 7x to both sides
-2x = -4
Divide by -2 to both sides.
x = 2

Answer:
Step-by-step explanation:
Given the sequence :
23, 19, 13, 5, -5.......
From the sequence, the common difference is unequal, as their is a constant Increment in the difference after successive numbers.
19 - 23 = -4
13 - 19 = -6
5 - 13 = -8
-5 - 5= -10
Hence an constant difference of - 2 after each successive difference.
Hence, this is a quadratic sequence
With the formula
an² + bn + c
The answer to this question is 0.
Hope this helps :)
