Answer:
u1 = 1
u6 = 31
un = 1 + 6(n - 1)
Step-by-step explanation:
Sn = 3n² - 2n
u1 = S1
3(1)² - 2(1)
3 - 2
1
u6 = S6 - S5
[3(6)² - 2(6)] - [3(5)² - 2(5)]
96 - 65
31
un = a + (n - 1)d
u6 = a + 5d
31 = 1 + 5d
5d = 30
d = 6
un = 1 + 6(n - 1)
I’m confused on what it is asking
I think it’s 3 out of 5
Because 20-8 is 12
12 is the number of beans that is not blue
12/20 simply to 3/5
Hope it helps

the mean of the data set would be 9
