Answer:

first three numbers are 22, 19 and 16

Step-by-step explanation:

The nth term is given by,

a_n =25-3n      (general expression for nth term)

To find first three terms , we need to put n=1,2 and 3 in  a_n =25-3n  as follows:

put n=1 , for first term

a_1 =25-3(1)

a_1 =25-3

a_1 =22

put n=2 , for second term

a_2 =25-3(2)

a_2 =25-6

a_2 =19

put n=3 , for third term

a_3 =25-3(3)

a_3 =25-9

a_3 =16

Therefore, first three numbers are 22, 19 and 16
