Answer:
149 is the 47th term in the given sequence.
Step-by-step explanation:
An = A1 + (n-1)d
In this problem, An is represented as A47, or the term we are looking to find,
A1 is the first number in the sequence, so in this case, it would be 11,
n is the term that is attached to An, in this case, it would be 47,
d is the common difference, or what number can I add or subtract to get the other number and all other numbers in the sequence, for this case it would be 3. (11+3=14, 14+3=17, 17+3=20)
Now, we plug in all numbers, and it would look like
11+(47-1)3
11+(46)3
11+138=149
