Explanation

For circular arrangement we use formula = (n - 1)!

Where n = number of people

Here n = 5 friends

So, (5 - 1)! = 4!

4! = 4 _ 3 _ 2 * 1 = 24

Total different circular arrangements = 24

Series: 5, 16, 49, ?

Check the pattern:

5 _ 3 + 1 = 15 + 1 = 16

16 _ 3 + 1 = 48 + 1 = 49

Rule: Multiply by 3 and add 1

Next term:

49 * 3 + 1 = 147 + 1 = 148

Next number = 148

Explanation

Day 1 = 5 GB

Day 2 = 10 GB 

Day 3 = 15 GB

Day 4 = 20 GB

The data increases by 5 GB every day.

This is an arithmetic series.

First term a = 5

Common difference d = 5

Number of days n = 15

Formula for sum = n/2 _ [2_a + (n-1)_d]

Put values:

Sum = 15/2 _ [2_5 + (15-1)_5]

Sum = 15/2 _ [10 + 70]

Sum = 15/2 _ 80

Sum = 15 * 40

Sum = 600

Total data in 15 days = 600 GB

Explanation

The pattern increases by 4 each time:

8 → 12 (+4)

12 → 16 (+4)

The next number should be 20, not 21.

Therefore, 21 is the incorrect number.
