To answer this question first you have to count the difference between the highest number with the lowest number.
In this case, the difference is: 40-12=28

After that, you need to determine the leaps in the sequence. In this case, there are 4 leaps.  
After that divide the difference with the leaps : 28:4=7
Therefore the sequence will be 12 , 19, 26, 33, 40

Mutleys journey began on a boat, 2 feet above sea level. He dove down to twelve feet below sea level and then returned to the su
Lubov Fominskaja [6]

Answer:

Mutley would start at 2 feet above sea level or +2, he would then travel 12 feet below sea level (-12) to then return to the surface of the ocean (0).  The integers from least to greatest:  -12, 0, 2.  Visual:

-12(dive level) * * * * * * * * * * * 0(sea level) * 2(boat)

Step-by-step explanation:

Using positive and negative integers, we can determine Mutleys journey above, below and at the surface of the ocean.  The surface of the ocean represents his 'origin' or starting point, which is 0.  The boat is above the surface or +2.  When Mutley dives below the surface, he is at a negative level of the ocean.  Think of it in terms of a number line - negative numbers are to the left of 0 and positive numbers are to the right of 0.  The further we go to the left on the number line, the lower our number.  In this case, -12 would be furthest to the left, then 0, followed by 2.

Naddika [18.5K]

1. Balance after 1 year with simple interest= 600 + (2.5 x 12) = 600 + 30 = $630

2. Balance after 1 year with compounded interest = P ( 1 + \frac{r}{n})^{nt}

= 600 ( 1 + \frac{0.05}{12})^{12}= 600 (1.0511) = $630.66 = approx. $630
