Answer correct for brainliest and also get a ! : -) answer a and b!

a) your iterative rule would be: 22,28,34,40 it is because there are 22 in first row and it is increasing by 6 at each step

b) Now, a(n) = 100, a=22, d=28-22 = 6

we know, a(n) = a+(n-1)d

 100 = 22+(n-1)6

 100-22 = 6n-6

  78+6 = 6n

  n = 84/6

  n= 14
