KS2 Primary Maths Age 13-17 - Ratio, Proportion and Algebra: Number Sequences - Explained

The video tutorial explains a number pattern problem where B is calculated based on A using a formula. The pattern involves multiplying A by 10 and subtracting 1 to get B. The tutorial walks through the pattern with examples, provides an alternative method using the 10 times table, and concludes with a reflection on the problem's difficulty.

What is the initial task given in the number pattern problem?

• To find the value of A when B is known

• To find the difference between A and B

• To determine a rule for B in terms of A

• To calculate the sum of A and B

In the examples provided, what operation is consistently applied to A to find B?

• Divide by 2 and add 10

• Multiply by 10 and subtract 1

• Multiply by 10 and add 1

• Add 5 and multiply by 2

What is the pattern rule for B in terms of A?

• B = 10 * A - 1

• B = 5 * A + 1

• B = A + 10

• B = A / 2 + 10

How does the 10 times table relate to the pattern rule?

• It is used to divide A

• It is used to multiply A

• It is used to add to A

• It is used to subtract from A

What was noted about the difficulty of the problem?

• Some students solved it correctly

• No students could solve it

• All students found it easy

• It was not attempted by students
