3√10 + 7√15 - 6√10 - 4√15
3√10 - 6√10 + 7√15 - 4√15
-3√10 + 3√15
The answer is B.
Answer:
a_n = 3 + a_n − 1 a_ n = 3 + a_ n − 1
Step-by-step explanation:
The first term is 8, so a_1 = 8
Each time we want a new term, we add on 3
8+3 = 11
11+3 = 14
14+3 = 17
17+3 = 20
23+3 = 26
and so on
This recursive step of adding on 3 to the prior term is written as this: an = 3+a_n-1 which says "to get the nth term, add 3 to the term just before the nth term"
The equation is y=2x+1 so plug in 43 for y
43=2x+1
42=2x
21=x!!
