Answer: -2, 2, 6, 10, 14
It is an Arithmetic sequence.
Step-by-step explanation:
Given Recursive formula :
, for n ≥ 1 and A(1) = -2.
Hence, the five terms of given sequence= -2, 2, 6, 10, 14
Since, there is common difference of 4 in two consecutive terms.
Therefore, it is an Arithmetic sequence.
Answer:
85° and 95°
Step-by-step explanation:
Given that , x and x + 10 are a pair of angles .
- If they will be pair of angles on the same line , then their sum will be 180° .
=> x + x + 10° = 180°
=> 2x = 180° -10°
=> 2x = 170°
=> x = 170°/2
=> x = 85° .
<h3><u>Hence </u><u>the </u><u>two </u><u>angles</u><u> </u><u>are </u><u>8</u><u>5</u><u>°</u><u> </u><u>and </u><u>9</u><u>5</u><u>°</u><u> </u><u>.</u></h3>
