What is the first term in algebra?

What is the first term in algebra?

The words “three times” tell us the first term is a number multiplied by three. In this expression, we don’t need a multiplication sign or parenthesis. Phrases like “a number” or “the number” tell us our expression has an unknown quantity, called a variable. In algebra, we use letters to represent variables.

What is the first term in a sequence?

Each term in a sequence has a position (first, second, third and so on). For example, consider the sequence {5,15,25,35,…} In the sequence, each number is called a term. The number 5 has first position, 15 has second position, 25 has third position and so on.

What does 3X mean in algebra?

3X is adding the value of ‘X’ three times i.e triple times. is multiplying the value of ‘X’ with itself 3 times.

What are the three terms of arithmetic sequence?

In an Arithmetic Sequence, the difference between one term and the next is a Common Difference: d . The terms are: a1,(a1+d),(a1+2d),(a1+3d),…, where a1 is the First Term and d is the Common Difference.

Is the first term 0 or 1?

Note: Sometimes sequences start with an index of n = 0, so the first term is actually a0. Then the second term would be a1. The first listed term in such a case would be called the “zero-eth” term. This method of numbering the terms is used, for example, in Javascript arrays.

What is the algebraic form of the arithmetic sequence?

The algebraic form of the arithmetic sequence is 4n+1. What are the first five terms? – Quora The algebraic form of the arithmetic sequence is 4n+1. What are the first five terms? 8 clever moves when you have $1,000 in the bank.

What is the sum of the first 5 terms of arithmetic sequence?

The sum of the first 5 terms of an arithmetic sequence is 60. What is the sequence? =>a =12 and by hit and trial d=1 for sum of the series to. be 60. =10,11,12,13,14. Ans. 9 lessons from millionaires who are good with money. Life would be a whole lot easier if someone would just Venmo us $1 million.

How do you find the nth term of an arithmetic sequence?

For any arithmetic sequence, first term has n=1. Hence first term is 6+2=8 Aliter: 6n+2 = 6n-6+8=8+6 (n-1). Comparing with the standard expression of nth term of an arithmetic progression [a+d (n-1)] we have, a=8, d=6 a (n)=the pattern of an arithmetic sequence where 6n+2 defines the nth term of any term in the sequence

What is the sequence if n starts at 1 and ends 5?

If n starts at 1 and ends at 5, the sequence would be: 4, 8, 12, 16, 20, since 1×4=4, 2×4=8, and so on. Now sum these up, and you get 60.
