20th term of sequence is 800
<em><u>Solution:</u></em>
Given sequence is 2, 8, 18, 32
To find: 20th term of sequence
Let us first find the pattern followed by sequence
So the next term is found by multiplying 2 with the square of location of term
<em><u>For nth term, we can represent by</u></em>
Where, n = 1, 2, 3, .........
<em><u>To find 20th term</u></em>
n = 20
Thus 20th term of sequence is 800
Answer:
3
Step-by-step explanation:
Answer:
10 x 15 = 150
Area of trapezoid:
10 + 20 = 30
30 x 5 = 150
20 - 15 = 5
150 divided by 2 ( x 1/2) = 75
75 + 150 = 225 square cm
Formula of a trapezoid:
B1(base1) + B2(base2) x H (Height) x 1/2 (basically dividing by 2)
Answer:
69 3/4
Step-by-step explanation:
The stock market goes down to 50 3/4 at the beginning of the day
At the end of the day it goes up to 120 1/2
Therefore total change in the stock market from the beginning to the end of the day can be calculated as follows
= 120 1/2 - 50 3/4
= 241/2 - 203/4
= 279/4
= 69 3/4
Hence the total change in the stock market from the beginning to the end of the day is
69 3/4
