Question

Here is a pattern. 121,120, 128,127,135,134,142,

a) Identify the rule in this pattern.
b) Find the next term in this pattern.
c) Create a number pattern with the same rule.

Answer 1

The pattern has two steps: subtract 1 from the previous number, then add 8 to the next number. Following this rule, the next term after 142 in the pattern is 141. A similar pattern starting with 100 would be 100, 99, 107, 106, and so on.

Step-by-step explanation:

The question involves identifying and continuing a number pattern. Given the sequence 121, 120, 128, 127, 135, 134, 142, let's break down the pattern rules:

1. Subtract 1 from the previous number
2. Add 8 to the resulting number

Following these rules:

• 121 (starting number)
• 121 - 1 = 120
• 120 + 8 = 128
• 128 - 1 = 127
• 127 + 8 = 135
• 135 - 1 = 134
• 134 + 8 = 142

Continuing the pattern, the next term after 142 is found by subtracting 1, which gives us 141 as the next term.

Creating a new pattern with the same rule, starting with the number 100:

• 100
• 100 - 1 = 99
• 99 + 8 = 107
• 107 - 1 = 106 (and so on...)
