Answer: The Given sequence is 9, 10, 11, 12
We need to find the expression to describe the sequence.
Let be the term of the sequence.
Let n represent the position of the term.
Let a be the first term in the sequence.
and d be the common difference between the sequence
Hence the expression to find the above sequence is given below;
when n=1 d= 1 a = 9
when n=2 d= 1 a = 9
when n=3 d= 1 a = 9
when n=3 d= 1 a = 9
Hence the expression is
Step-by-step explanation:
In this case you would have numbers that are not whole, so you have decimals.
Ex of how you estimate numbers:
5.45 estimate is 5
3.20 estimate is 3
7.50 estimate is 8
1.89 estimate is 2
Everything that is beyond .50 decimals is rounded up to the next no. 7.50 is estimated to 8 because the decimals are .50 or above. Same goes for the other ex. 1.89 which will become 2.
Everything that is under the .50 decimals we rounded down to the same number, 5.45 has the decimals under .50 that means that the number is rounded down to 5. same applies to 3.20 which will become 3.
Hope you understand the explanation!
Cheers
