bcalle
an = a1 + (n - 1)(d)
a1 = the first term in the sequence
d = common difference
n = term
a25 = 3 + (25 - 1)(6)
a25 = 3 + (24)(6)
a25 = 3 + 144
a25 = 147

Answer:

25th Term of the Given Sequence is 147.

Step-by-step explanation:

We are given with an arithmetic sequence: 3 , 9 , 15 , 21 , 27 , ...

We have to find 25th term of the sequence.

First term of the sequence , a = 3

Common difference of the sequence , d = 9 - 3 = 6

We know that nth term of Arithmetic Sequence is given as below,

[tex]a_n=a+(n-1)d[/tex]

So,

25th term of the sequence , [tex]a_{25}=3+(25-1)6=3+24\times6=3+144=147[/tex]

Therefore, 25th Term of the Given Sequence is 147.
