Find the missing number.
7, 11, __, 19, 23
Show answer & explanation
Correct answer: C
Explanation
Given series: 7, 11, __, 19, 23
Difference between consecutive terms:
11 − 7 = 4
19 − 15 = 4
23 − 19 = 4
So, the pattern is adding 4 each time.
Hence, the missing term = 11 + 4 = 15.
The correct answer is option 3.
