Given:
The series = 30,48,68,90,
To Find:
Number after 90
Solution:
The first term is 30.
In the given series, the difference between two consecutive terms is increasing by two.
This can be explained as -
30 + 18 = 48
48 + 20 = 68
68 + 22 = 90
90 + 24 = 114
Answer: The number after 90 is 114, and the series will be - 30,48,68,90, 114.
