Explanation

The series alternates between numbers and letters:  

Numbers increase by 8: 1, 9, 17, ... next number is 25  

Letters increase by 8 in the alphabet: A (1), I (9), ... next letter is Q (17)  

So, next term is Q.

Explanation

The Sun is the central body that the Earth orbits

Likewise, the Earth is the central body that the Moon orbits.

Explanation

First pair’s first letters jump by +4: A→E→I→M ⇒ pairs AB, EF, IJ, MN.

Letters after the slash go +2 in alphabet positions: m(13), o(15), q(17), s(19).

So the missing term is IJ/q.

Explanation

Step 1: Find the pattern in differences
6 − 2 = 4
14 − 6 = 8
30 − 14 = 16
62 − 30 = 32

So the differences are: 4, 8, 16, 32 → doubling each time.

Step 2: Find the next difference
32 × 2 = 64

Step 3: Add to the last term
62 + 64 = 126

Explanation

Adding two equal fractions (1/4 + 1/4) results in doubling the numerator:

1/4 + 1/4 = 2/4 = 1/2

Explanation

1/8 + 1/8 + 1/8 + 1/8

= 4/8

= 1/2

Explanation

x = √2 − 1  

x² = (√2 − 1)²  

= 2 − 2√2 + 1  

= 3 − 2√2
