Answer:
D
Step-by-step explanation:
A rational number will either end or repeat forever like the first three, but the fourth one, pi, will go on forever and never repeat, making it irrational.
We know, S = n/2 [ a + l ]
Here, a = 45
l = 108
Calculation of n:
a(n) = a + (n - 1)d
108 = 45 + (n - 1)1
108 - 45 = n - 1
63 + 1 = n
n = 64
Now, substitute in the expression:
S = 64/2 [ 45 + 108 ]
S = 32 [ 153 ]
S = 4896
In short, Your Answer would be 4896
Hope this helps!
An = A1 + (N-1)d
A1 is the first term (in this case 2)
d is the common difference (what is the difference between all consecutive even numbers? 2)
N is the number of terms to find (in this case 29)
An = 2 + (29-1)2 = 58
I would say none of the above, unless you typed it wrong. The sum is the product of the number of terms minus one and two, plus two more. So it's almost answer B but not really. Good luck with this one.
There is no solution since ln(0) is undefined
