Finding Patterns(4th Grade > Mathematics ) Questions and Answers
Explanation:-
Answer: Option C. -> 16U:
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 obtainedby 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 is1A, 4E, 7I, 10M, 13Q, 16U, ...
Explanation:-
Answer: Option B. -> 34:
B
The given sequence is6, 10, 14, 18…
Let us calculate the difference between two consecutive terms:
10 - 6 = 4
14 - 10 = 4
18 - 14 = 4
We observe that the difference between two consecutive terms is 4 and each term is 4 more than the term preceding it.
So, the8th term of the sequence = 6 + (8 - 1)×4 = 6 + 7×4 = 6 + 28 = 34
Explanation:-
Answer: Option A. -> Odd number pattern:
A
The given pattern is 3,5,7,9……
Odd numbers are numbers which have 1, 3, 5, 7, 9 intheirunits place.
We observe that each term in the above sequence is an odd number, alsoeach term is 2 more than the term preceding it.
So, the above sequence is an example of an odd number pattern.
Explanation:-
Answer: Option D. -> 20, 24 and 28:
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.
Explanation:-
Answer: Option A. -> Square number pattern:
A
1,4,9,16,25,36…….
The square number sequence is a pattern of numbers which is asfollows:
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.
Explanation:-
Answer: Option A. -> 29:
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 grainsto the 7th bird.
