Missing   Number Puzzle - 1

Simpson is going to receive a donut if he finds the unknown value and is calling for your assistance.
Can you find the unknown value and help Simpson get his donut?

SOLUTION!

Solution -

C1=(A1*B1)+B1
Implies C1=(2*1)+1=3
In the same way
C2=(A2*B2)+B2
C3=(A3*B3)+B3
So the unknown C4 will be equal to
C4=(A4*B4)+B4
C4=(6*2)+2=12+2=14
