    Answer:the sum of the first 30 terms is 3750

    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 = 9

    d = 8

    Therefore, the sum of the first 30 terms, 30 would be

    S30 = 30/2[2 * 9 + (30 - 1) 8]

    S30 = 15[18 + 29 * 8]

    S30 = 15[18 + 232]

    S30 = 15[18 + 232]

    S30 = 3750

    The equation is arithmetic so y = 8x+1. plug in 30 for x. y = 8 (30) + 1 and y=241!
