Question : 6 of 75

Marks: +1, -0

13, 24, 46, 79, 123,?

Solution:

Concept:

The series follows a pattern of increasing differences.

Explanation:

Find the differences between consecutive terms:

24 - 13 = 11

46 - 24 = 22

79 - 46 = 33

123 - 79 = 44

The differences increase by

11

each time:

11, 22, 33, 44

So, the next difference is

44 + 11 = 55

Therefore, the next term is

123 + 55 = 178

Answer:

178
