Concept

One of the fundamental concepts in Arithmetic is sequence and series. A sequence is an itemized collection of components in which repeats of any kind are permitted, whereas a series is the total of all elements. One of the most common instances of sequence and series is an arithmetic progression.

Given

Given that the series 11, 12, 16,25, 41,66,

Find

We need to find the missing number in the series

Solution

So , According to the series ,

11, 12, 16,25, 41,66,----

Therefore, We can say that

Each Number is the preceding Number multiplied by the square of the Number in sequence.

We can see that

11+1*1 = 12

12+2*2 = 16

16+3*3 = 25

25+4*4 = 41

41+5*5 = 66

66+6*6 = 102

Hence the Missing number is 102
