Arithmetic Progressions

Problem

Analytics

Fredo recently learnt about Arithmetic Progressions. Seeing his keen interest in the topic, his teacher gave him a task. Fredo is initially given two tables:

1.**first** : It consists of first terms of arithmetic progressions.

2.**diff** : It consists of numbers which can act as the difference between two elements in the arithmetic progression.

The task is:

For every entry **a** in the **first** table, you have to find the smallest number **d** greater than **a** in the **diff** table and then print the \(5^{th}\) term of the arithmetic progression whose first term is **a** and difference is **d**.

Both the tables have unique entries.

Table : **first**

Table: **diff**
