find the wrong term 8,39,76,120,160,207
Answers
Answer:
The wrong term is 120.
Step-by-step explanation:
The logic behind the series can be found if the differences are determined.
The differences are found to be:
31,37,44,40,47
From this we can see that 40 seems to be an odd one as it is not following the increasing trend of numbers.
Now from this, we need to trace back to the original number series and find that the wrong number has to be either 120 or 160, but since the last difference is correct, 120 is the wrong number.
Answer is 120
explanation:
the difference between the numbers can be observed carefully to get the logic behind it
8 39 76 120 160 207
+31 +37 +44 +40 +47
but if u observe carefully the trend in the difference should be the prime numbers starting from 31
+31 +37 +41 +43 47
this has to be there to get the series as
8 39 76 117 160 207
hence 117 should the number instead of 120
