Answer 1

Answer:

x=5

Step-by-step explanation:

2*(2x)=x+2+2x+3

x=5

Answer 2

Answer:

5

Step-by-step explanation:

since they are in AP, they have a common difference. Let this common difference be d

since 2x and 2x+3 are in AP, 2x + d = 2x+3

therefore, d=3

now, since x + 2 and 2x are in the same AP

x +2 + d= 2x

x + 2 + 3=2x

x + 5=2x

2x - x=5

x=5
