    Answer: D. 60100

    Step-by-step explanation:

    The formula for determining the sum of n terms of an arithmetic sequence is expressed as

    Sn = n/2[2a + (n - 1) d]

    Where

    n represents the number of terms in the arithmetic sequence.

    d represents the common difference of the terms in the arithmetic sequence.

    a represents the first term of the arithmetic sequence.

    From the information given,

    n = 200 terms

    a = 2

    d = 3

    Therefore, the sum of the first 200 terms, S200 would be

    S200 = 200/2[2 * 2 + (200 - 1) 3]

    S200 = 100[4 + 597)

    S200 = 100 * 601 = 60100
