Question

Identify the rule and the next two numbers in the sequence to complete the given pattern.
14, 24, __, __, __, __, __, 84

• A. Add 5; 34, 44, 54, 64, 74
  
• B. Add 10; 34, 44, 54, 64, 74
• C. Add 10; 44, 54, 64, 74, 94
  
• D. Add 5; 29, 34, 44, 59, 79
  

Answer 1

The correct option is B Add 10; 34, 44, 54, 64, 74

Say: Let us identify the number of jumps needed to complete the pattern and find the missing numbers.

Steps:
$\bullet$ The first number is 14 and the next given number is 24.
$\bullet$ We can see that 10 is added to 14 to get 24, so we add 10 to each number in the pattern to get the next number.
$\bullet$ The number after 24 will be 24 + 10 = 34, then $44,44+10=54,54+10=64,64+10=74$
$\bullet$ So, we add 10 to each number to get the next number and the complete sequence is $14,24,\underset{–}{34},\underset{–}{44},\underset{–}{54},\underset{–}{64},\underset{–}{74},84.$
$\bullet$ Hence, option C is the correct answer.

WB: If required, use the whiteboard to identify the rule and find the missing numbers as shown.
