Answer:
3rd, 5th and 17th terms are 14, 20, 56 respectively.
Step-by-step explanation:
The given question is incomplete; find the complete question in the attachment.
In this question explicit formula has been given as,
f(n) = 8 + 3(n -1)
We have to find the 3rd, 5th and 17th term of the sequence described by the explicit formula given above.
For 3rd term,
Substitute n = 3 in the formula,
f(3) = 8 + 3(3 - 1)
= 8 + (3 ×2)
= 8 + 6
= 14
Similarly. for n = 5,
f(5) = 8 + 3(5 - 1)
= 8 + 3(4)
= 8 + 12
= 20
For n = 17,
f(17) = 8 + 3(17 - 1)
= 8 + 3(16)
= 8 + 48
= 56
Therefore, 3rd, 5th and 17th terms are 14, 20 and 56 respectively.
