Answer 2

The solution is 3145

Step-by-step explanation:

The given series is 9,81,89,623,629,

We will try to find a sequence in the given series.

First number is 9 and the next is 81

So it implies $9\times9=81$

The third number is 89 that is $81+8=89$

The fourth number is 623 that is $89\times7=623$

The fifth number is 629 that is $623+6=629$

Now if we observe the number we get a sequence, the numbers are being multiplied and added in a decreasing order.

The second number is multiplied by 9 while in the third number 8 that is one less than 9 is added.

Similarly in the fourth number it is multiplied by 7 that is one less than 8, and in the fifth 6 is added that is one less than 7.

Thus the next number would be $629\times5=3145$ and the next number would $3145+4=3149$
