First, you want to figure out the pattern of the rows of chairs. Clearly, here the pattern is to add 7 to the previous number.
Now, you want to continue the pattern 4 more times
6,14,22,_,_,_,_
6,14,22,29,36,43,50
Now you add all these numbers together to get the answer.
6 + 14 + 22 + 29 + 36 + 43 + 50 = ?
6 + 14 + 22 + 29 + 36 + 43 + 50 = 200
There are 200 chairs set out for the wedding guests.
