Answer:
The 50th term is 288.
Step-by-step explanation:
A sequence that each term is related with the prior by a sum of a constant ratio is called a arithmetic progression, the sequence in this problem is one of those. In order to calculate the nth term of a setence like that we need to use the following formula:
an = a1 + (n-1)*r
Where an is the nth term, a1 is the first term, n is the position of the term in the sequence and r is the ratio between the numbers. In this case:
a50 = -6 + (50 - 1)*6
a50 = -6 + 49*6
a50 = -6 + 294
a50 = 288
The 50th term is 288.
Answer:
$40 is the difference. One is positive(W1), one is negative(W2). Therefore, you subtract.
Step-by-step explanation:
You subtract week ones profit and week twos profit.
65 - 25 = $40
You subtract because she had a negative profit for week two and/or a profit below 0.
17x = 85
x = 85/17
x = 5.
Hence x = 5 makes above equality true.
Hope this helps!
