Answer:
First term: a
Second term: a+d
Third term:a+2d
Step-by-step explanation:
An expression that can model the first three terms of any arithmetic sequence in terms of just a and d is aₙ = a + (n - 1)d.
What is an arithmetic sequence?An ordered group of numbers with a shared difference between each succeeding term is known as an arithmetic sequence. For instance, the common difference in the arithmetic series 3, 8, 13, 18, and 23 is 5. An arithmetic progression is another name for an arithmetic sequence.
How to solve this problem?Let the a be the initial term of a sequence and d be the common difference, then the nth term of any arithmetic sequence can be written as aₙ = a + (n - 1)d.
If we want first three terms of any arithmetic sequence, then we have to put n = 1, 2, 3 in the above expression.
So, for n = 1, a₁ = a + (1 - 1)d = a + 0d = a
for n = 2, a₂ = a + (2 - 1)d = a + d
for n = 3, a₃ = a + (3 - 1)d = a + 2d
Therefore, an expression that can model the first three terms of any arithmetic sequence in terms of just a and d is aₙ = a + (n - 1)d.

solve the question z + 18 = 27.
9???????????????????????????????
Answer:
I'm going to guess that you are trying to find z. If so, Z is 9.
Step-by-step explanation:
Z + 18 = 27
Subtract 18 on both sides
Z + 18 = 27
Z - 18 = - 18
Z = 9

How many times greater is the value of the 6 in 618,923 than the 6 in 27.652
The value of 6 in 618,923 is 1,000,000 or 1 million times greater than that of 6 in 27.652.
What is Place Value?Place value of a digit in a number is defined as the value of that digit according to the position where it stands.
Place value of a whole number of digits from right to left can be expressed as ones, tens, hundreds, thousand, etc.
Place value of a decimal number after the decimal point from left to right can be expressed as tenths, hundredths, thousandths, etc.
The given numbers are 618,923 and 27.652.
Place value of 6 in 618,923 = 6 × 100,000
That is 6 hundred thousands is the place value.
Place value of 6 in 27.652 = 6 × 1/10 = 6 × 10⁻¹
This is at the tenth place.
6 × 100,000 = 6 × 10⁻¹ × 1,000,000
So 6 × 100,000 is 1,000,000 times greater than 6 × 10⁻¹.
Hence the value of 6 in 618,923 is 1,000,000 times greater than the 6 in 27.652.
