If (4, x+2, 2x+1, 19) are in an arithmetic progression, what should be the value of (x)?

Answer and explanation

Correct answer: No value

The total difference from (4) to (19) is (15), so (d=5), the second term should be (9) and the third (14); this gives (x=7) and (x=\frac{13}{2}). Therefore no single (x) is possible.
