Question

the nth term of a sequence is 25-3n what are the first three terms

Answer 1

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
