An arithmetic sequence is that in which the consecutive terms share or have the same difference commonly referred to as the "common difference". The terms in the arithmetic sequence always starts with the term 0 or the initial value. In this item, the value of n should be greater than or equal to. Therefore the answer is the second choice.
If we are to get the first term of the arithmetic sequence, it will become,
first term:
a0 = (-1) + 7(0 - 1) = -8
Therefore, the first term is equal to -8.
For #16, every input by +1 has an output of +7.
9 + 7 = 16
16 + 7 = 23
23 + 7 = 30.....
The percent of water would be 40%
Subtract the amount you have from the amount you need:
2 cups - 1 3/8 cups
Subtract the whole cup first:
2 cups -1 cup = 1 cup
8/8 = 1
Rewrite 1 as 8/8 then subtract the 3/8 you have:
8/8 - 3/8 = 5/8
You need 5/8 cup more
