The first term a = 1, 

Common difference, d: 7 - 1 = 6.

a(n) =  a + (n -1)d,        

For 30th term.      =  1 + (30 -1)*6
 
                             =  1 + 29*6 = 1 + 174 = 175

What do I do for this question
padilas [110]

Answer:

Step-by-step explanation:

a + 9 = 15

a = 15 - 9

a = 6

c + 9 = 16

     c = 16 - 9

     c = 7

d = c + 9

   = 7 + 9

  = 16

e = d + 15

  = 16 + 15

e = 31

P(selecting a boy) = total boy /total pupils = 16/31
