The answer would be 32. take your 26 and add 18 then subtract 12. then rework it forward if you don't understand.
Answer:
0.30555555....
Step-by-step explanation:
(The fives keep on coming, this is a repeating decimal.)
The distance traveled by the balloon in every minute makes an arithmetic sequence with a first term equal to 40 ft and common difference equal to 20. The nth term of an arithmetic sequence is calculated by,
an = a1 + (n - 1) x d
Substituting,
an = 40 + (15 - 1) x 20 = 320
Thus, the answer is letter B. 320 feet.
