1, 2, 3, 6, 47, 94, 141, 282, 1609, 3218, 4827, 9654, 75623, 151246, 226869, 453738
Step-by-step explanation:
I looked it up
I'm guessing the repeating part is 89 at the end, so that
Then
###
An arguably quicker way without using geometric series:
16n2−10n+22
0.9375
divide the numerator by the denominator
ex. 15 divided by 16
b.
sin 30 = 1/2
sin (-30) = -1/2.
30 degrees is in quadrant I where the sine is positive and -30 degrees is in quadrant IV where the sine is negative.
