Answer:
350 adult tickets were sold
Step-by-step explanation:
Let "a" represent the number of adult tickets sold. Then the number of student tickets is (a+69) and the total number of tickets sold is ...
a + (a+69) = 769
2a = 700 . . . . . . . . subtract 69
a = 350 . . . . . . . . . divide by 2
350 adult tickets were sold.
Sum of series of G.P. = Sn = a(1-rⁿ) / 1-r
Here, a = 5
r = 1/5
Substitute their values into the expression:
Sn = 5(1-1/5⁵) / 1 - 1/5
Sn = 5*5/4 [1-1/3125]
Sn = 25/4 [ 3124/3125]
Sn = 781 / 125
In short, Your Answer would be 781/125 in fraction form
or 6.248 in decimal form
Hope this helps!
Answer:
62°
Step-by-step explanation:
Complementary angles by definition are two or more angles that add up to 90°. So we must do 90°-62° to get the missing angle which is 62°.

Check the forward differences:
-1 - 1 = -2
-7 - (-1) = -6
-25 - (-7) = -18
Notice how the differences appear to follow a geometric progression with common ratio 3. So if 
denotes the 
th term in the given sequence, we seem to have
so that the general pattern for 
would be
Then the sequence is given recursively by
The first 10 terms in the sequence would be
1, -1, -7, -25, -79, -241, -727, -2185, -6559, -19681
