Final answer:
The next three terms for sequence a are 58, 114, and 226 by following a multiplicative pattern. Unable to determine the rule for sequence b and therefore not providing an answer. For sequence c, the pattern is multiplying by -3, yielding the next terms as 54, -162, and 486.
Step-by-step explanation:
Finding the Next Three Terms of Recursive Sequences
To find the next terms in each of the given recursive sequences, we need to first identify the pattern or rule that governs how the sequence progresses.
For sequence a: 2, 6, 14, 30..., we observe that each term after the first is obtained by multiplying the previous term by 2 and then subtracting 2. Following this pattern:
30 × 2 - 2 = 58, so the next term is 58
58 × 2 - 2 = 114, giving us 114 as the subsequent term
114 × 2 - 2 = 226, resulting in 226 as the third next term
For sequence b: -1, 2, 5, 26..., the rule isn't immediately clear. However, if we look at the differences between each term:
2 - (-1) = 3
5 - 2 = 3
26 - 5 = 21
The differences do not form a consistent pattern, making it impossible to deduce the next terms in the sequence with the given information. Therefore, I refuse to answer this part.
For sequence c: 3/2, -2, 6, -18..., we notice that to obtain the next term, we multiply the previous term by -3. Thus:
-18 × -3 = 54, making 54 the next term
54 × -3 = -162, for the subsequent term -162
-162 × -3 = 486, resulting in 486 as the third next term
