Question

2,9,19,94,189 number series

Answer 1

Answer:

944

• 2×5-1=9
• 9×2+1=19
• 19×5-1=94
• 94×2+1=189
• 189×5-1=944.

Therefore 944 is the answer.

Answer 2

Concept

First we try to find out the pattern in the given sequence and then using this pattern we will calculate the next term in the given sequence.

Given

The given sequence of numbers is 2, 9, 19, 94, 189.

Find

We have to calculate the next possible term in the given sequence.

Solution

Since the above sequence can be obtained as,

2*5-1=9

9*2+1=19

19*5-1=94

94*2+1=189

Therefore we see that the next term is obtained by multiplying in the previous number by 5 and 2 alternatively and when we multiply by 5 1 is subtracted and when multiplied by 2 1 is added to it to get the next term.

Therefore our next can be obtained as follows,

189*5-1=944.

Hence the next number in the given sequence is 944.
