Answer:
72.3
Step-by-step explanation:
Given that:
The arithmetic sequence:

The first term of the sequence
= 3 since k = 0
i.e (3 + 0.26(0)) = 3
The last term of the sequence
= 6.64
i.e (3+ 0.26(14)
= (3 + 3.64)
= 6.64
Total no of terms = 15 i.e from 0 to 14
∴
The partial sum of the arithmetic sequence = 

= 72.3
