The awnser is (3, 1)
Hope this helps!!!!!!!!!!!!!!!!!
A19 = -92
a20 = 6
common difference = d = a20 - a19
d = 6 - (-92)
d = 6 + 92
d = 98
formula for nth term
an = a1 + (n-1)d
put n = 20
a20 = a1 + (20-1)d
6 = a1 + 19(98)
6 = a1 + 1862
6 - 1862 = a1
-1856 = a1
a1 = -1856
now nth term:
an = a1 + (n-1)d
an = -1856 + (n-1)98
an = -1856 + 98(n-1)
Answer:
Step-by-step explanation:
The answer is 11.
x - 30 = 14 - 3x
4x = 44
x = 11
A number (x) decreased by 30 (x - 30) is the same as (=) 14 decreased by 3 times the number (14 - 3x).
I think you should ask for help by posting in sections instead of the assignment as a whole
