CBSE Class 4 Maths Patterns And Designs Worksheet Set 01

Question 1. Observe the number pattern and extend:

a) 2462, 2464, 2468 , ________, _________ , ________
Answer: 2472, 2476, 2480
In simple words: The numbers increase by adding 4 each time (\(2462 + 4 = 2466\), but looking closely at standard increments, the given sequence is 2462, 2466, 2470... wait, let's check the difference: \(2464 - 2462 = 2\) and \(2468 - 2464 = 4\)? Re-evaluating: the given OCR is 2462, 2464, 2468. Actually, let's look at the differences: \(2464 - 2462 = 2\), \(2468 - 2464 = 4\). If the rule is adding 2, then 4, then 6, then the next terms are \(2468 + 6 = 2474\), \(2474 + 8 = 2482\), \(2482 + 10 = 2492\). Alternatively, if it is a simple sequence of even numbers: 2470, 2472, 2474. Let us provide consecutive even numbers: 2470, 2472, 2474.
Exam Tip: Always find the difference between consecutive numbers to identify the underlying rule.

Question 1(b). 7353, 7358, 7363, ____________, ___________, _________
Answer: 7368, 7373, 7378
In simple words: Each number increases by 5.

Exam Tip: Check the ones digit; alternating 3 and 8 indicates counting by fives.

Question 1(c). 3726, 3763, 3746, ________, ____________, __________
Answer: 3783, 3766, 3803
In simple words: The pattern alternates by adding and subtracting specific values or follows a two-part alternating sequence.

Question 1(d). 4111, 5111, 6111, ____________, __________, __________
Answer: 7111, 8111, 9111
In simple words: The thousands place increases by 1 each time, adding 1000 to the previous number.

Exam Tip: Identify which place value is changing to quickly find the next terms.

Question 1(e). 6250, 6300, 6350, __________, __________, ___________
Answer: 6400, 6450, 6500
In simple words: Each number increases by 50.

Exam Tip: Adding 50 means the hundreds and tens digits change in a predictable cycle.

Question 1(f). 4510, 4514, 4518, ___________, ___________, __________
Answer: 4522, 4526, 4530
In simple words: Each number increases by 4.

Exam Tip: Verify the difference between the first two terms: \(4514 - 4510 = 4\).

Question 1(g). 2345, 2346, 2347, __________, ___________, ___________
Answer: 2348, 2349, 2350
In simple words: This is a simple counting sequence where each number increases by 1.

Exam Tip: Consecutive counting numbers always have a common difference of 1.

Question 1(h). 9323, 9322, 9321, ___________, __________, ____________
Answer: 9320, 9319, 9318
In simple words: This is a backward counting sequence where each number decreases by 1.

Exam Tip: Pay close attention to whether the sequence is increasing or decreasing.

Question 1(i). 5214, 5224, 5234, __________, ___________, ____________
Answer: 5244, 5254, 5264
In simple words: The tens digit increases by 1 each time, meaning we add 10 to each number.

Exam Tip: Look at the tens place to spot increments of 10 easily.

Question 1(j). 1946, 1951, 1956 , _________, __________, ____________
Answer: 1961, 1966, 1971
In simple words: Each number increases by 5.

Exam Tip: Check \(1951 - 1946 = 5\) to confirm the step size.

Question 2. Observe the pattern and extend:
Answer:
The visual pattern shows alternating faces: smiling face, sad face, smiling face, followed by blank circles. Extending the alternating face pattern:
1. Sad face
2. Smiling face
3. Sad face
4. Smiling face
In simple words: The pattern alternates between a smiling face and a sad face repeatedly.

Exam Tip: For shape or picture patterns, identify the repeating unit or core cycle.
