Each row increases by 4, so the second row would be 46 +4 which equals 50. Then the 3rd row would be 50 +4.
So the 1st number is a(1) = 46 ( row 1 has 46 bricks)
The common difference is adding 4 bricks, so d = +4
The function becomes a(n) = a(1) +(n-1) * d
where n is the number of the row you want to find the total of.
Now you want to know the 12th row so replace n with 12:
a(12) = 46 + (12-1)*4
a(12) = 46 + ( 11*4 )
a(12) = 46 + 44
a(12) = 90 bricks
a + (n - 1)d
a is 46, the initial.
n is the nth term, or in this case 12
d is difference, which is 4
plug this info in....
46+ (12-1)4
=90
