In a certain code language

I am good 134

Life is good 524

Then good is represented as ____

A.

3

B.

4

C.

1

D.

5

#### SOLUTION

Solution : B

Iamgood134Lifeisgood524

In both the sentences good is represented as 4.

Hence  good =   4

What kind of number pattern is this: 3, 5, 7, 9…?

A.

Odd number pattern

B.

Even number pattern

C.

Prime number pattern

D.

Bulk sequence

#### SOLUTION

Solution : A

The given pattern is 3,5,7,9……

Odd numbers are numbers which have 1, 3, 5, 7, 9 in their units place.

We observe that each term in the above sequence is an odd number, also each term is 2 more than the term preceding it.

So, the above sequence is an example of an odd number pattern.

A man fed pieces of grains to birds in a pattern of prime numbers starting with 7 for the first bird. How many grains did the 7th bird get?

A.

29

B.

27

C.

23

D.

19

#### SOLUTION

Solution : A

Prime numbers are the set of numbers which is divisible by 1 or the number itself.

The pattern of prime numbers starting from 7 is

7,11,13,17,19,23,29……

So in this pattern, the number in the 7th position is 29.

So he fed 29 grains to the 7th bird.

Which pattern does this sequence follow: 1, 4, 9, 16, 25…?

A.

Square number pattern

B.

Pentagonal number pattern

C.

Hexagonal number pattern

D.

Triangular number pattern

#### SOLUTION

Solution : A

1,4,9,16,25,36…….

The square number sequence is a pattern of numbers which is as follows:

The number in nth position = n×n

In the above pattern:

The number in 1st position = 1×1 = 1

The number in 2nd position = 2×2 = 4

The number in 3rd position = 3×3 = 9

The number in 4th position = 4×4 = 16

The number in 5th position = 5×5 = 25

So, the above sequence is a square number pattern.

Find the next term: 1A, 4E, 7I, 10M, 13Q …

A.

15U

B.

16T

C.

16U

D.

15V

#### SOLUTION

Solution : C

The given sequence is 1A, 4E, 7I, 10M, 13Q …

We can split the above sequence into two sequences:

1, 4, 7, 10, 13, ...

A, E, I, M, Q, ...

For the number pattern, we observe that each term is 3 more than the preceding term.

So, the next term in the sequence will be 13 + 3 = 16

The alphabets are:

A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, W, X, Y, Z

The sequence  A, E, I, M, Q, ... the next term in the sequence is obtained by skipping three alphabets and jumping to the fourth one, starting with A.

So, the next alphabet in the sequence is U.

On combing the sequence of the numbers and the alphabets, next term in the sequence is 16U.

So, the pattern is 1A, 4E, 7I, 10M, 13Q, 16U, ...

Find the 10th term of the sequence: 2, 8, 14, 20…

A.

50

B.

54

C.

56

D.

52

#### SOLUTION

Solution : C

The given sequence is  2, 8, 14, 20…

Let us calculate the difference between two consecutive terms:

8 - 2 = 6

14 - 8 = 6

20 - 14 = 6

We observe that the difference between two consecutive terms is 6 and each term is 6 more than the term preceding it.

So,the 10th term of the sequence = 2 + (10 - 1)×6 = 2 + 9×6 = 2 + 54 = 56

Hence, the 10th term of the sequence is 56.

Find the next figure in the given pattern:

A.

B.

C.

D.

#### SOLUTION

Solution : B

In the pattern above, the arrow flips by 90 in clockwise direction.

So the next figure in the pattern will be

Find the next two figures in the given pattern:

A.

B.

C.

D.

#### SOLUTION

Solution : A

In the pattern above, a red arrow is followed by two green arrows.

So, the next two figures in the above pattern are a red arrow followed by a green arrow.

Find the next 3 terms in the sequence:
4, 8, 12, 16...

A. 17, 18 and 19
B. 18, 20 and 22
C. 19, 22 and 25
D. 20, 24 and 28

#### SOLUTION

Solution : D

The sequence follows:
4, 8, 12, 16...
We can see, the terms are consecutive multiples of 4.

4 × 1 = 4
4 × 2 = 8
4 × 3 = 12
4 × 4 = 16
4 × 5 = 20
4 × 6 = 24
4 × 7 = 28

So, the next three terms are 20, 24, and 28.

What sequence/pattern is followed?
1, 2, 4, 8, 16 ...

A. Arithmetic sequence
B. Color pattern
C. Geometric sequence
D. Language pattern

#### SOLUTION

Solution : C

The sequence follows: 1, 2, 4, 8, ...
Each term is multiplied with 2 to get the succeeding term.
1 × 2 = 2
2 × 2 = 4
4 × 2 = 8
8 × 2 = 16

It is a geometric sequence.
