Question

Iggy used this rule to make a number pattern.

  • Start with 2.

  • To get to the next number, multiply by 2 then add 3.

What is the sum of the first three numbers in Iggy's pattern?

Worked Solution

First write down the pattern:

First number = 2
Second number = 2 ×\times 2 + 3 = 7
Third number = 2 ×\times 7 + 3 = 17


Then find the sum of the numbers

Sum of first 3 terms = 2 + 7 + 17 = 26

Question

Ellie used this rule to make a number pattern.

  • Start with 4.

  • To get to the next number, multiply by 3 then takeaway 1.

What is the sum of the first three numbers in Ellie's pattern?

Worked Solution

First write down the pattern:

First number = 4
Second number = 3 ×\times 4 - 1 = 11
Third number = 3 ×\times 11 - 1 = 32


Then find the sum of the numbers

Sum of first 3 terms = 4 + 11 + 32 = 47

Question

Boss used this rule to make a number pattern.

  • Start with 10.

  • To get to the next number, multiply by 4 then add 5.

What is the sum of the first three numbers in Boss's pattern?

Worked Solution

First write down the pattern:

First number = 10
Second number = 4 ×\times 10 + 5 = 45
Third number = 4 ×\times 45 + 5 = 185


Then find the sum of the numbers

Sum of first 3 terms = 10 + 45 + 185 = 240

Question

Joyce used this rule to make a number pattern.

  • Start with 12.

  • To get to the next number, multiply by 4 then takeaway 8.

What is the sum of the first three numbers in Joyce's pattern?

Worked Solution

First write down the pattern:

First number = 12
Second number = 4 ×\times 12 - 8 = 40
Third number = 4 ×\times 40 - 8 = 152


Then find the sum of the numbers

Sum of first 3 terms = 12 + 40 + 152 = 204
