Answer:
Tn = 3n-1
T6 = 17
Step-by-step explanation:
Given the arithmetic sequence;
2, 5...
first term a = 2
Common difference d = 5-2 = 3
nth term of an AP is expressed as Tn = a + (n-1)d
Tn = 2 + (n-1)(3)
Tn = 2 + 3n-3
Tn = 3n-1
Get the 6th term
T6 = 3(6)-1
T6 = 18-1
T6 = 17
Hence the 6th term of the sequence is 17
The wall has an area of 8 * 100 = 800 square feet
So therefore 800/400 = 2 gallons are required the answer is C
Answer:
Step-by-step explanation:
Let m represent the number of months since joining the newspaper.
Let a represent the total number of articles he has published.
The columnist had already published 46 articles before joining a newspaper. Since then, he has published 11 more articles every month. This means that in m months, the total number of articles he would have published is
a = 46 + 11m
Therefore, when m = 6,
a = 46 + 11 × 6 = 46 + 66
a = 112
