Answer:
- 3108
Step-by-step explanation:
The sum to n terms of an arithmetic series is
= 
[ 2
+ (n - 1)d ]
Substitute the given values into the formula
= 
[ (2 × - 26) + (23 × - 9) ]
= 12 ( - 52 - 207 )
= 12 × - 259 = - 3108
I would say that the "n"th term of the sequence is 41, as the pattern increases by 10 every term.
Here's what you have to do: multiply. 54.9×12= 658.8. So, he traveled 658.8 miles in twelve hours.
