Answer 2

Therefore the series can be either 4,2,2,4,16,6 or 4,2,2,4,16,8.

Given:

Given series 4,2,2,4 16, x

Let us assume the required number to complete the series be 'x'.

To Find:

Complete the series.

Solution:

We can simply solve this numerical problem by using the following process.

Given Series 4,2,2,4,16,x

Now the given series is not in Arithmetic Progression as there is no common difference.

The given series first decreases from 4 to 2 and remains constant from 2 to 2 and then increases from 2 to 4. So there is no specific sequence.

Hence there might be two sequences,

First Sequence: Odd Digits: 4,2,16

Second Sequence: Even Digits: 2,4,x

⇒ 4,2,2,4,16,x

Now we need to find x.

Here there are two possibilities

Possibility 1: 2, 2+2, 4+2 ⇒ 2,4,6

Hence final series becomes 4,2,2,4,16,6

Possibility 2: 2, 2²,2³ ⇒ 2,4,8

Hence final series becomes  4,2,2,4,16,8

Therefore the series can be either 4,2,2,4,16,6 or 4,2,2,4,16,8.
