Which recursive formula can be used to generate the sequence shown, where f(1) = 5 and n > 1? 5,–1, –7, –13, –19,

5, -1, -7, -13, -19

 -6   -6  -6   -6     the difference between the numbers is -6

 ; where a₁ is the first term, d is the difference, and n is the term

f(1) = 5

      = 11 - 6

       = 5

 TRUE

(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

17.08

correct me if i am wrong.
