Answer:
2.326
Step-by-step explanation:
This does not look easy to factor, so I'd suggest using the quadratic formula:
-1 plus or minus sqrt( 1-4(3)(-5) )
x = -----------------------------------------------
2*3
-1 plus or minus sqrt(61)
= ------------------------------------
6
Thus, there are 2 real, unequal, irrational roots / solutions.
You are adding 2 each time.
You are trying to find the 30th term, in which 4 are shown.
Subtract 4 from 30
30 - 4 = 26
Multiply 26 with 2
26 x 2 = 52
Add 52 to the last number given (0)
0 + 52 = 52
52 is your answer
hope this helps
