Find the common ratio 24,18,37/2,81/8

Note: The third term of the sequence should be instead of , otherwise the sequence has no common ratio.

Given:

The given sequence is

To find:

The common ratio of the given sequence.

Solution:

The quotient of each pair of consecutive terms are:

Similarly,

And,

Therefore, the common ratio of the given sequence is or 0.75.

78.59 is the mean

step-by-step explanation:

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
