) Write the value of x for which (x + 2), 2x, (2x + 3) are three consecutive terms of an AP?
) Find the coordinate of the midpoint of the line segment joining the​

Answer 1

Step-by-step explanation:

2). As (X+2), 2x and (2X+3) are in AP.

There fore their common difference is sane.

common difference of 1st and 2nd term = the common difference of 2nd and term.

2x - (X+2) =. (2x+3) - 2x

2x - x - 2 = 2x + 3 - 2x

X - 2 = 3

X = 3 + 2

X = 5
