Pattern-c
Numbers Involved: 32 and 64
Quick Calculation: The pattern is mostly made of 32, but the bottom part has 64s. You
can multiply the number of 32s and 64s separately and then add them together to get
the total.
Solution: Numbers Involved: 32 and 64
Step 1: Counting the numbers
We have 28 "32s" and 9 "64s" in the pattern.
Step 2: Multiply the numbers
Multiply the number of 32s by 32:
28 × 32 = 896
Multiply the number of 64s by 64:
9 × 64 = 576
Step 3: Add them together896 + 576 = 1472
Final Answer: The total sum for the numbers in this pattern is 1472.
Pattern-d
Numbers Involved: More squares with dots
Quick Calculation: Similar to Pattern b, count the squares with dots and multiply. Pay attention
to the different colours, as they might represent different groups.
Solution
Step 1: Identify the squares
Purple squares have 4 dots each.
Red squares have 6 dots each.
Step 2: Count the number of squares
Purple squares: 20 squares with 4 dots.
Red squares: 9 squares with 6 dots.
Step 3: Multiply the dots
Dots in purple squares: 20 × 4 = 80
Dots in red squares: 9 × 6 = 54
Step 4: Add them together
80 + 54 = 134
Final Answer: The total number of dots in the pattern is 134.
