Math Problem Statement

4 √3, 9√3, 14√3, 19√3

Solution

Given the sequence: 43,93,143,1934\sqrt{3}, 9\sqrt{3}, 14\sqrt{3}, 19\sqrt{3}

we need to find the general rule or nth term of this sequence.

Analyzing the Sequence

Let's extract the coefficients of 3\sqrt{3}: 4,9,14,194, 9, 14, 19

This sequence is: 4,9,14,194, 9, 14, 19

This sequence is an arithmetic sequence with the first term a=4a = 4 and the common difference d=5d = 5.

General Term of the Arithmetic Sequence

The nth term of an arithmetic sequence is given by: an=a+(n1)da_n = a + (n-1)d

Substituting the values for aa and dd: an=4+(n1)5a_n = 4 + (n-1) \cdot 5 an=4+5n5a_n = 4 + 5n - 5 an=5n1a_n = 5n - 1

Incorporating 3\sqrt{3}

Since each term of the sequence is multiplied by 3\sqrt{3}, we multiply the general term of the arithmetic sequence by 3\sqrt{3}: Tn=(5n1)3T_n = (5n - 1)\sqrt{3}

General Rule

Therefore, the general rule for the nth term of the sequence is: Tn=(5n1)3T_n = (5n - 1)\sqrt{3}

Tip: When dealing with sequences, always look for patterns in differences or ratios to identify the type of sequence (arithmetic, geometric, etc.). This will help in deriving the correct formula for the nth term.
