Question

What’s missing from this sequence of numbers?
4, 8, 12, 20, ??, 52

Answer 1

4+8 = 12
8 + 12 = 20
20 + 12 = 32

Ans is 32

Answer 2

32 is the missing term of the given sequence.

Step-by-step explanation:

In any given sequence, we need to find the pattern which is followed across the whole sequence. This pattern can be multiples, factors, differences, additions, divisions or indirect patterns.

There will particular order where all the entities follow each other. The entities in the sequence are called terms.

Sequences are used as basis for series (innumerable collection of entities) which are used widely in higher mathematical applications. They can be studied as puzzles, study of numbers etc.

They can be finite or infinite depending upon their boundaries. The length of the sequence is the number of terms in the sequence.

Now, let us consider the given sequence of terms 4, 8, 12, 20, -- , 52

We can see that third number is obtained by adding the first two terms.

4 + 8 = 12

8 + 12 = 20

12 + 20 = 32

So, 32 is the next term required.

Let us validate with the next term.

20 + 32 = 52 …….validated…
