If an arithmetic progression has first term 2, last term 50, and 13 terms, what is its sum?

Answer and explanation

Correct answer: 338

For an arithmetic progression, the sum of n terms can be found using Sₙ = n/2 × (first term + last term). Substituting n = 13, the first term 2, and the last term 50 gives S₁₃ = 13/2 × (2 + 50) = 13/2 × 52 = 13 × 26 = 338. Therefore, option B is correct; the other values result from an arithmetic or formula error.
