The first term is 23, and the common difference is 4 ; n= 5
the 5th term is 4 differences from the 1st term
To find the nth term of an arithmetic sequence, you can use the formula:
an = a1 + (n-1)d
Where:
an is the nth term
a1 is the first term
n is the number of terms
d is the common difference
In this case, the first term (a1) is 23, the common difference (d) is 4, and we want to find the 5th term (n = 5). Plugging these values into the formula, we have:
a5 = 23 + (5-1) * 4
Simplifying:
a5 = 23 + 4 * 4
a5 = 23 + 16
a5 = 39
Therefore, the 5th term of the arithmetic sequence is 39.
