Given the functions f(n)=25 and g(n)=3(n-1) combine them to create an arithmetic sequence an and solve for the 12th term.

Given functions : and

When we combine then to  create an arithmetic sequence , we get

To solve for 12th term , we put n= 12 in , we get

Hence, the value of 12th term of = 58

(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
