here are the first five terms of an arithmetic sequence 1 3 5 7 9 find in terms of n an expression for the nth term of this sequence​

= 2n - 1

Step-by-step explanation:

The nth term of an arithmetic sequence is

= a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 1 and d = a₂ - a₁ = 3 - 1 = 2 , then

= 1 + 2(n - 1) = 1 + 2n - 2 = 2n - 1

the answer is somewhere there guys it really . there im just not gonna answer

but i'm guessing ur first option tho

answer is 144
