A.) First 5 terms are: 4(1) + 5, 4(2) + 5, 4(3) + 5, 4(4) + 5, 4(5) + 5 = 4 + 5, 8 + 5, 12 + 5, 16 + 5, 20 + 5 = 9, 13, 17, 21, 25
b.) 25th term = 4(25) + 5 = 100 + 5 = 105
sum of the first 25 terms = 25/2(9 + 105) = 25/2(114) = 285
c.) The sequence is an arithmetic sequence because, the sequence increases by addition of 4.
<span>C. Youthful
"Child-like" as a word can best be replaced by the adjective youthful. It is the correct part of speech to fit into the rest of the sentence, and it means basically the same thing. Acting like a child is acting as one did in youth, so youthful and child-like are very close synonyms. </span>
I would say it's A, because like the question stated, his curiosity, tends to overcome his judgement. But the thing about this is that this leads into C, because his curiosity comes before his judgement, so he is risking his life, to be curious...
Hope this helped!! :)
