Question

Use the explicit formula an = a1 + (n – 1) • d to find the 250th term of the sequence below.

57, 66, 75, 84, 93, ...
A.2334
B.2307
C.2241
D.2298

Answer 1

D. 2298

Explanation:

Did the work on paper, and tested it. It's correct. Have a great day.

Answer 2

For this case we have the following equation:
an = a1 + (n - 1) • d
Where,
a1 = 57
d = 66-57 = 9
For the term number 250 we have:
n = 250
Substituting the values:
a250 = 57 + (250 - 1) * 9
a250 = 2298
Answer:
D.2298
