how to calculate the first hundred terms of a sequence
Answer:
Question: what is the sum of the first 100 whole numbers?? how am i supposed to work this out efficiently? thanks
The question you asked relates back to a famous mathematician, Gauss. In elementary school in the late 1700’s, Gauss was asked to find the sum of the numbers from 1 to 100. The question was assigned as “busy work” by the teacher, but Gauss found the answer rather quickly by discovering a pattern. His observation was as follows:
1 + 2 + 3 + 4 + … + 98 + 99 + 100
Gauss noticed that if he was to split the numbers into two groups (1 to 50 and 51 to 100), he could add them together vertically to get a sum of 101.
1 + 2 + 3 + 4 + 5 + … + 48 + 49 + 50
100 + 99 + 98 + 97 + 96 + … + 53 + 52 + 51
1 + 100 = 101
2 + 99 = 101
3 + 98 = 101
.
.
.
48 + 53 = 101
49 + 52 = 101
50 + 51 = 101
Gauss realized then that his final total would be 50(101) = 5050.
The sequence of numbers (1, 2, 3, … , 100) is arithmetic and when we are looking for the sum of a sequence, we call it a series. Thanks to Gauss, there is a special formula we can use to find the sum of a series:
S is the sum of the series and n is the number of terms in the series, in this case, 100.
Hope this helps!

Historically many ideas concerning cells have been examined leaving three to be incorporated into the cell theory which of the following is not part of the cell theory
Answer:all life form contains more than one cell
Explanation: thats the only question that's not true
Historically, many ideas concerning cells have been examined, leaving three to be incorporated into the cell theory except that all life forms are made up of more than one cell as the life forms can either be single or multicellular.
What is the significance of the theory behind the cell?Cell theory, a foundational concept in biology, states that all living organisms are made of cells, and these cells come from pre-existing cells and not from anywhere else. All these postulates support the idea that cells are the basic building blocks of life and that life can only be generated through the replication process.
Hence, historically, many ideas concerning cells have been examined, leaving three to be incorporated into the cell theory except that all life forms are made up of more than one cell as the life forms can either be single or multicellular.

Sea ice forms no
Ocean water
evaporates
A freshwater
stream enters
the ocean
Ocean Salinity Increases
Ocean Salinity Decreases
Answer:
1. in ocean salinity increases
2. ocean salinity decreases
3.ocean salinity increases
4. ocean salinity decreases.
Explanation:
The salinity of the ocean is increased by the evaporation of ocean water and the formation of sea ice.
The salinity of the ocean is decreased by the melting of sea ice and entering a freshwater stream into the sea.
What is Ocean Salinity?Ocean salinity may be defined as the presence of the concentration of salts in the ocean. A Hydrometer is an instrument that determines the salinity of the ocean.
The addition of freshwater streams into the ocean and melting of ice reduce its salinity, as it makes the sea water less dense.
On contrary, the left two processes are opposite to above and thus are responsible for increasing the salinity of the ocean.
Therefore, it is well described above.

Explanation: The alternating sequence of complementary bases is what determines traits found in organisms
In DNA molecule, the information is found in kinds of nitrogenous bases that form complementary nucleotide pairs.
What are the functions of DNA?Deoxyribonucleic acid (DNA) is an organic chemical that contains genetic information and instructions for protein synthesis. It is found in most cells of every organism.
DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins.
DNA is made of nucleotides. A nucleotide has two components: a backbone, made from the sugar deoxyribose and phosphate groups, and nitrogenous bases, known as cytosine, thymine, adenine, and guanine.
