In an arithmetic series, the terms of the series are equally spread out. for example, in 1 + 5 + 9 + 13 + 17, consecutive terms are 4 apart. if the first term in an arithmetic series is 3, the last term is 136, and the sum is 1,390, what are the first 3 terms? a. 3, 10, 17 b. 3, 23, 43 c. 3 , 36.333 , 70 d. 3, 69.5, 136 2 e. 3, 139, 1,251
