Question

First term 127, term-to-term rule: "subtract 1 then divide by 2"

A) 63
B) 62
C) 31
D) 30

Answer 1

The term-to-term rule applied to the first term (127) gives the next term: (127 - 1) / 2 = 63. Therefore, option A) 63 is the correct answer.

Step-by-step explanation:

The question given involves a sequence where the first term is 127 and the term-to-term rule is to 'subtract 1 then divide by 2' to find the next term. To apply this rule, we start with the first term, 127, then subtract 1, which yields 126. Following the rule, we then divide 126 by 2, resulting in 63 as the next term in the sequence. Therefore, the correct answer is A) 63.
