In which row and column will the number 83 appear?

Row 10 and in column F

Step-by-step explanation:

rows 1 and 3 are decreasing and we are looking for an increase so we can cross those out immediately.

However we do see a pattern in rows 2 to 4 (add 8) so if we add 8 for 3 more rows than we get 37 but add 8 more and we get 45.

from 37 to 43 is 6 more than 37 so we have 4 columns but if we add 3 more we get the 6 columns also column f.

Hope this helps!

the answer would be  

a.

3: 1
