# Rules For Letter and Symbol Series Questions and Online Test

**Number
Series**

In this section, a number series will be given, out of which

one number or alphabet would be missing. So you have to complete the series by

applying rules or patterns.

**The Rules For The Number Series**

1. Every

number can be a multiple of the other numbers.

2. In

every number, something may be increased or decreased to get the 2nd term or

number.

3. The

numbers can be divided to get the preceding numbers.

4. The

number may be doubled or squared to get the next term or number.

5. The

square root of the numbers can be taken to get the next term.

6. Sometimes,

odd numbers are followed by even numbers and even numbers or terms are followed

by an odd number to get the next one.

7. something

may be added, subtracted, or divided, or multiplied to get the next term.

8. Sometimes,

odd number is doubled or squared, the other would be multiplied 3 times, the

fourth term would be multiplied 4 times, etc. and then something can be added

or subtracted.

**Wrong Numbers:**

**Rules:**

1.

In this type,

numbers are arranged in series and sequences.

2.

One term in

the series or sequence will be wrong

3.

You will be

asked to find the wrong number or term in a series, from the alternative given.

Therefore, interpret or decode a general pattern followed in the series or

sequence.

4.

And finally,

decide the wrong term.

**Alphabet Series**

A sequence of alphabet or series will be given in such a

series or sequence, which follows a specific pattern throughout the series.

Therefore you have to interpret or decode the pattern followed in series and

complete the series, by choosing the correct alternatives given in the

question.

**Rules For The
Alphabet Series**

1.

Some of the rules that would be followed to find the

next term in the alphabet series are given below.

2.

keep the order of letters with respect to their number

or position. for example A= 1 …………….. AND Z=26 and vice versa and

also Z=1 and A=26 in reverse sequence.

3.

in

some questions, some letters are omitted in sequence like ABC-, EFG-, IJK-. in

this series D and H are omitted.

4.

in

some problems, an equal number of letters or words are omitted e.g in ADG, two

consecutive terms are omitted.

5. In some cases, one letter will follow the next letter and another letter would be

preceding it. E.g in BCA, the letter C is following B and A is preceding To B.

6.

sometimes,

there could be a repetition of letters in a set or group of letters, e.g in

AAB, ABC-, in 1st term one letter is repeated twice that is a in the next term

the letters are not repeated, so in the 3rd term there will be a repetition of

the letter that would be CCD.

7.

sometimes,

the numbers would be mixed with alphabets, in this, the numbers might refer to

the position of a letter in the set.
