2, 11, 20, 29...
Which term in this sequence is 227?
A) 18th
B) 24th
C) 25th
D) 26th

Answer 1

D) 26th

Explanation:

Let a = the first term, n = the nth term, d = the difference between each term, and l = the last term. Use the formula a + (n - 1)d. Plug in the values and solve. 227 = 2 + (n - 1)(9), 225 = (n - 1)(9), n = 26.

Answer 2

The closest answer would be 25 but there isn’t an exact answer here because it would be a few decimal points off
