I don't get this question. Because if it is this simple, the two whole numbers are 40 and 42
the answer is definitly C
Given =
n=6,
r=1/4
a=2
Sn = a+ar+ar²+ar³+ar⁴+ar⁵= 2+0.5+0.125+0.03125+0.0078125+0.00195~ 2.67
You draw the reference angle of 45° but clockwise. The exact value of sin(-345°) is 1/√2.
