You need to clear the fractions by multiplying every term by the LCD of both fractions, which would be 16. 80 and 48/16 inches and 144 and 16/8. that's 83 and 146 so the answer is 63 inches need to be cut off

the first term of an arithmetic sequence is equal to 200 and the common differencence is equal to -10. find the value of the 20t

olga_2 [115]

Answer:

The value for 20th term is 10.

Step-by-step explanation:

First, you have to find the formula for the sequence.

$an = a + d(n - 1)$

$let \: a = 200,d = - 10$

$an = 200 - 10(n - 1)$

$an = 200 - 10n + 10$

$an = - 10n + 210$

Given that the formula of this sequence is an = -10n + 210. Next, you have to find 20th term :

$let \:n = 20$

$20th \: term = - 10(20) + 210$

$20th \: term = - 200 + 210$

$20th \: term = 10$
