To solve this number series, we need to identify the pattern and continue it to find the missing term.
Pattern:
Looking at the given numbers, we can observe the following pattern:
- The first number is 80, which is followed by a number 10.
- The second number is obtained by subtracting 10 from the previous number (80 - 10 = 70).
- The third number is obtained by adding 5 to the previous number (70 + 5 = 75).
- The fourth number is obtained by subtracting 15 from the previous number (75 - 15 = 60).
- The pattern continues in the same way.
Using this pattern, we can find the missing term in the series.
Solution:
To find the missing term, we need to continue the pattern by adding or subtracting the corresponding numbers to the previous term.
- The last number in the given series is 60.
- To find the missing term, we need to subtract 15 from the previous number (60 - 15 = 45).
- Therefore, the missing term is 45.
Verification:
Let's verify our answer by checking if it follows the pattern.
- The missing term is 45.
- The next number in the series should be obtained by adding 5 to the previous number (45 + 5 = 50).
- Now, we can check if the pattern continues: 80, 10, 70, 15, 60, 45, 50.
- The pattern is indeed continuing, so our answer of 45 is correct.
Conclusion:
The missing term in the given number series is 45. Therefore, the correct answer is option A) 20.
