# (Python Example for Citizen Data Scientist & Business Analyst)

Write a Python program to print the length of the series and the series from the given 3rd term, 3rd last term and the sum of a series.

```Sample Data:
Input third term of the series: 3
Input 3rd last term: 3
Sum of the series: 15
Length of the series: 5
Series:
1 2 3 4 5```

Sample Solution:

Python Code:

``````tn = int(input("Input third term of the series:"))
tltn = int(input("Input 3rd last term:"))
s_sum = int(input("Sum of the series:"))
n = int(2*s_sum/(tn+tltn))
print("Length of the series: ",n)

if n-5==0:
d = (s_sum-3*tn)//6
else:
d = (tltn-tn)/(n-5)

a = tn-2*d
j = 0
print("Series:")
for j in range(n-1):
print(int(a),end=" ")
a+=d
print(int(a),end=" ")
``````

Sample Output:

```Input third term of the series: 3
Input 3rd last term: 6
Sum of the series: 36
Length of the series:  8
Series:
1 2 3 4 5 6 7 8
```

More Sample Output:

```Input third term of the series: 3
Input 3rd last term: 3
Sum of the series: 15
Length of the series:  5
Series:
1 2 3 4 5```
