Answer:
option D is true.
Step-by-step explanation:
Given the sequence
7, 12, 17, 22, ...
An arithmetic sequence has a constant difference 'd' and is defined by
Computing the differences of all the adjacent terms
The difference between all the adjacent terms is the same
so
as
Thus, the nth term of the arithmetic sequence will be:
Therefore, option D is true.
Answer:
74 degrees

Answer:
27 years
Step-by-step explanation:
21 × 2 = 42
42 - 15 = 27
179 and 180
consecutive numbers have a difference of 1 between them
let the 2 numbers be n and n + 1, then
n + n + 1 = 359
2n + 1 = 359 ( subtract 1 from both sides )
2n = 358 ( divide both sides by 2 )
n = 179 and n + 1 = 179 + 1 = 180
the 2 pages are 179 and 180
