Explanation

Given numbers = 1, 5, 7, 9, 11

Add 13

New series = 1, 5, 7, 9, 11, 13

Total numbers = 6, which is even

For even numbers, median = average of middle 2 numbers

Middle 2 numbers = 3rd and 4th number = 7 and 9

Median = (7 + 9) / 2

= 16 / 2

= 8

Explanation

Sequence = Yellow, Green, Blue, White

Total colours in one cycle = 4

Find position 38

Divide 38 by 4

38 / 4 = 9 remainder 2

Remainder 2 means 2nd colour in the sequence.

1st = Yellow

2nd = Green

3rd = Blue  

4th = White

So 38th position colour = Green

Explanation

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
