Answer:
The 25th term of the sequence is 147
Step-by-step explanation:
For an nth term in an arithmetic sequence
U(n) = a + (n - 1)d
Where
n is the number of terms
a is the first term
d is the common difference
From the above sequence
a = 3
d = 9 - 3 = 6
So the 25th terms for the sequence is
U(25) = 3 + ( 25 - 1) 6
= 3 + 24(6)
= 3 + 144
The final answer is
= 147
