Question
What are the next three numbers in given sequences by following the rule?
Rule: subtract 8
- 76, 68, 60
- 74, 68, 60
- 74, 66, 58
- 72, 64, 56
Hint:
We are given a sequence of numbers. We have been told that the rule used to form the sequence is to subtract 8. We have to continue the sequence and find the next three numbers. We will use the rule to find the required numbers.
The correct answer is: 74, 66, 58
The given sequence is 98, 90, 82
We have to find the next three terms in this sequence.
Rule: Subtract 8
To find the next term, 8 is subtracted from the previous term.
We will see how it works.
98 – 8 = 90
90 – 8 = 82
Now, let’s find the next terms.
The last term from the above sequence is 82
So, we will subtract 8 from it.
82 – 8 = 74
74 – 8 = 66
66 – 8 = 58
The complete sequence will be 98, 90, 82, 74, 66, 58
And the option which is '74, 66, 58’, is the required option.
For such questions, we should know the basic operations. When the rule used to write the pattern is not mentioned, we have to use all four operations to check the pattern. The operations are addition, subtraction, division, and multiplication.
