This is quite easy, but anyway:
In order, they are
3, 4, 4, 5, 5, 5, 5, 7, 7
7 - 3 = 4
4 would be the range
-16 + 5n = -7(-6 + 8n) + 3 Given
-16 + 5n = 42 - 56n + 3 Distribute
-16 + 5n = 45 - 56n Collect like terms
61n = 61 Add 56n to the left side and add 16 to the right side
n = 1 Divide 61 from both sides
The answer is n = 1. Remember that when you have a number beside two or more numbers in parentheses, you have to distribute, or multiply the number outside the parentheses by each number inside the parentheses.
Hope this helps!

Answer:
119
Step-by-step explanation:
Put the given values in the formula for the general term, and do the arithmetic.
an = a1 +d(n -1) . . . . . first term a1, common difference d
a14 = 2 +9(14 -1) = 119
The 14th term is 119.
21/50; 420/1000=42/100 simplify it and it is 21/50
