What number should replace the question mark in the following series: 450, 473, 519, 588, 680, 795, ?

A933 ✓ Correct

B950

C138

D82

Correct answer: (A) 933

Explanation

The next number is 933.

The differences form an arithmetic pattern: 23, 46, 69, 92, 115.

Each difference rises by 23.

473-450=23, 519-473=46, 588-519=69, 680-588=92, 795-680=115.

The next difference is 115 + 23 = 138.

795 + 138 = 933.
