Answer:
c.) 38
Step-by-step explanation:
[tex]\sum\limits_{n=3}^6 a_n[/tex] means "summation of the all the elements starting from the 3rd element to the 6th element".
The 3rd element in the series is 14, and the 6th element is 5; we have to add these and all the elements between them together.
∴ [tex]\sum\limits_{n=3}^6 a_n[/tex] = 14 + 11 + 8 + 5
= 38
