For an arithmetical sequence, the first term is 2 and the common difference is 3….

Correct Answer: Option B

Explanation

a = 2, d = 3 and n = 11
To find S_{n/sub> = (frac{n}{2}) [2a + (n – 1) (delta)] = (frac{11}{2}) [2(2) + (11 – 1) 3] = (frac{11}{2})n [4 + 10(3)] = (frac{11}{2})(34)
= 11 x 17
= 187}
