Question

The next number in the pattern \[ - 62, - 37, - 12,......\] is
A. 25
B. 13
C. 0
D. -13

Answer 1

Hint: Here we first will observe the sequence of the pattern given. The pattern has a repetition to be observed. There is a difference of 25 in the two numbers such that if we add 25 to the first number if the pattern we get the second number. And the same process is repeated for the rest of the series. So we have to add 25 to the last number to get the answer.

Complete step by step solution:
We are given the number pattern as \[ - 62, - 37, - 12,......\]
Now see that \[ - 62 + 25 = - 37\]
This is the second number of the series.
Now again \[ - 37 + 25 = - 12\]
This is the next number in the series.
So at last we will add 25 to last the number to get the answer
\[ - 12 + 25 = 13\]
This is our answer. So option B is the correct answer.
So, the correct answer is “Option B”.

Note: Here note that the difference is of positive 25 but the answer was negative such that the greater number has minus sign. At last when we add 25 to the last number; 25 is greater so we will give the sign of greater number to the answer. Thus from option B and D we choose B as correct. Sometimes the key solution is a double difference like the difference is taken in the second lap.so do observe carefully!
