The following is an A.P 9,x,y,z,25 find (a)the values of x,y,z (b)60 term
Answered by Bosnian
In an Arithmetic Progression:

an = a1 + ( n - 1 ) d

where

a1 = the initial term

d = the common difference of successive members

an = the nth term

In your A.P:

9 , x , y , z , 25

a1 = 9

a5 = a1 + 4 d = 9 + 4 d = 25

4 d = 25 - 9

4 d = 16

d = 16 / 4

d = 4

Now:

x = a2 = a1 + d = 9 + 4 = 13

y = a3 = a1 + 2 d = 9 + 2 ∙ 4 = 9 + 8 = 17

z = a4 = a1 + 3 d = 9 + 3 ∙ 4 = 9 + 12 = 21


a60 = a1 + 59 d

a60 = 9 + 59 ∙ 4 = 9 + 236 = 245
