Question

12,15,21
8,7,26
?,41,34
Find the missing.

Answer 1

We will try to find pattern

We will  look at the column

Third column:

21 , 26 , 34

now, we can add them

$21+26+34=81$

we can also write it as

$21+26+34=81=9*9$

Second column:

15 , 7 , 41

now, we can add them

$15+7+41=63$

we can also write it as

$15+7+41=63=9*7$

First column:

we can see that second term of multiplication is decreased by 2

Let's assume missing term as x

12 , 8 , x

now, we can add them

$12+8+x=20+x$

we can also write it as

so, our next term is 9*5

$12+8+x=20+x=9*5$

now, we can solve for x

$20+x=9*5$

$20+x=45$

$x=25$

so, the missing term is 25...........Answer
