**Type I: **

How to find the missing term or next term in (number or letter or figure) series to continue the given series?

- Identify the (descending or ascending) order of series. Observe the pattern using operations: addition, subtraction, multiplication, and division, skip counting and reverse counting.
- Identify the order of alphabetical series either from A to Z or Z to A.
- Numbering of alphabets either starts from A or starts from Z.
- Skipping letters.

**Type II:**

How to find the missing term in the pattern?

- To find the missing term in the pattern, identify the rule followed in rest of the given terms in pattern using mathematical operations (+, -, x), skip counting and reverse counting.

**Type III:**

How to find the missing part in the figure pattern?

- Complete the figure pattern by drawing its incomplete part in the pattern.

**EXAMPLE**

**1. Find the missing number in the given number pattern below. **

(a) 2 (b) 3 (c) 4 (d) 5

**Explanation (b): **

First we carefully study the two given complete patterns.

In the first pattern, the middle term is the sum of difference between the top and bottom number & left and right number.

\[(11-5)+(8-7)=6+1=7\]

Similarly, in second pattern \[(8-4)+7-6)=4+1=5\]

Hence, in third pattern the missing number is \[(9-7)+(9-8)=2+1=3\].

**2. Find the missing number in the series below: **

3, 6, 11, 18, 27____?____, 51,_____?____

(a) 30, 55 (b) 34, 60 (c) 38, 66 (d) 42, 71

**Explanation (c): **

Rule followed in the series is:

Difference between consecutive terms are consecutive odd numbers.

**3. Which of the following options will complete the figure (X)? **

(a) (b) (c) (d)

**Explanation (b): **

Complete the pattern given in the question by drawing its incomplete part.
