Answer:
16
Step-by-step explanation:
First, substitute the values of the variables into the expression:
3(y + 4) - (x - 1)
3(2 + 4) - (3 - 1)
Now, simplify both parentheses:
3(6) - 2
18 - 2
Finally, simplify:
16
Answer:
200
Step-by-step explanation:
the above is an arithmetic progressions
number of terms of an AP = a+( n -1 )d
a= first term= 8
d= common difference= 12-8= 4
49th term:
= 8+(49-1)4
= 8+(48)4
= 8+192= 200
therefore, the 49th term is 200
