Three numbers 3, q and 5 are in arithmetic progression if q = ?1. 42

1.	Three numbers 3, q and 5 are in arithmetic progression if q = ?1. 42. 53. 34. None of these
Answer» Correct Answer - Option 1 : 4 CONCEPT : Three numbers x, y, and z are in arithmetic progression if and only if : 2y = x + z. CALCULATION: Given: Three numbers 3, q and 5 are in arithmetic progression As we know that three numbers x, y, and z are in arithmetic progression if and only if : 2y = x + z. ⇒ 2q = 3 + 5 ⇒ 2q = 8 ⇒ q = 4 Hence, option (1) is the correct answer.

Three numbers 3, q and 5 are in arithmetic progression if q = ?1. 42. 53. 34. None of these

Answer» Correct Answer - Option 1 : 4

CONCEPT :

Three numbers x, y, and z are in arithmetic progression if and only if : 2y = x + z.

CALCULATION:

Given: Three numbers 3, q and 5 are in arithmetic progression

As we know that three numbers x, y, and z are in arithmetic progression if and only if : 2y = x + z.

⇒ 2q = 3 + 5

⇒ 2q = 8

⇒ q = 4

Hence, option (1) is the correct answer.
