The above posts apply a formula for arithmetic sequences.
However, if you don't know that formula, you can also solve the question by looking for a pattern.

term1 = 14
term2 = 14 + 9
term3 = 14 + 9 + 9
term4 = 14 + 9 + 9 + 9
term5 = 14 + 9 + 9 + 9 + 9
.
.
.
.
term41 = 14 + (sum of forty 9's)
= 14 + (360)
= 374
= D

Cheers,
Brent

The numbers in this sequence end with 4,3,2,1,0,9,8,7,6,5,4,3,2,1......
In other words, after 10 terms, the units digits will repeat. So the 41st term will be a value ending in 4. Only answer is D

\(a = 14, d = 9\)
41st term = \(a + 40d = 14 + 40(9) = 14 + 360 = 374\). Ans - D.
