Answer 1

• Given:- 3 4 5

3 7 12

3 ? 22

• To find:- The missing number.

• Solution:- According to the series

the format is llike

C1R1+C2R1= C2R2

C1R1+C2R1+C3R1= C3R2 [C= column and R= Row & 1,2,3... are column and row number]

So,3+4=7 & 3+4+5= 12

this format would be followed for next row also, so the format would be

C1R2+C2R2= C2R3

C1R2+C2R2+C3R2= C3R3

So, 7+3= 10 & 7+3+12=22

So the final answer is 10 .
