Select the first five terms in the arithmetic sequence an = 4n, starting with n =
a_n=4n+1
To find the first five terms of an arithmetic sequence with the formula an = 4n, we can start with n = 1 and continue until n = 5.
Step 1: Substitute n = 1 into the formula an = 4n:
a1 = 4(1) = 4
Step 2: Substitute n = 2 into the formula an = 4n:
a2 = 4(2) = 8
Step 3: Substitute n = 3 into the formula an = 4n:
a3 = 4(3) = 12
Step 4: Substitute n = 4 into the formula an = 4n:
a4 = 4(4) = 16
Step 5: Substitute n = 5 into the formula an = 4n:
a5 = 4(5) = 20
Therefore, the first five terms in the arithmetic sequence an = 4n starting with n = 1 are: 4, 8, 12, 16, 20.
To find the first five terms in the arithmetic sequence an = 4n, we can start with a given value for n and calculate the corresponding terms. The formula an = 4n means that each term in the sequence is obtained by multiplying the corresponding value of n by 4.
Let's start with n = 1:
a1 = 4(1) = 4
Now, for n = 2:
a2 = 4(2) = 8
For n = 3:
a3 = 4(3) = 12
For n = 4:
a4 = 4(4) = 16
For n = 5:
a5 = 4(5) = 20
So, the first five terms in the arithmetic sequence an = 4n are: 4, 8, 12, 16, 20.
If n = 1, term(1) = 4
if n = 2, term(2) = 8
if n = 3, term(3) = 12
