To find the 8th term in the sequence 15, 24, 42, 78, 150, we first identify a pattern in the differences between consecutive terms. The differences are 9, 18, 36, and 72, which suggest that the differences themselves are doubling (approximately). Continuing this pattern, the next differences would be 144 and 288. Thus, the 6th term would be 150 + 144 = 294, the 7th term would be 294 + 288 = 582, and the 8th term would be 582 + 576 = 1158. Therefore, the 8th term is 1158.
