Answer:
- 5, 2, 9, 16 and d = + 7
Step-by-step explanation:
to obtain the first four terms substitute n = 2, 3, 4 into the recursive formula
f(1) = - 5 ← given
f(2) = f(1) + 7 = - 5 + 7 = 2
f(3) = f(2) + 7 = 2 + 7 = 9
f(4) = f(3) + 7 = 9 + 7 = 16
common difference d = 16 - 9 = 9 - 2 = 2 - (- 5) = 7
<u>Answer</u>:
x = 70 ;
y = 50 .
_____________________________________________________
Explanation:
_____________________________________________________
y = 50 ; since vertical angles are congruent.
180 – (50 + 60) = x ; since all angles in any triangle add up to 180 degrees.
↔ x = 180 – (50 + 60) = 180 – (110) = 70.
