Diketahui barisan bilangan sebagai berikut :                     6, 10, 14, 18, .... Suku ke-11 barisan tersebut adalah …Soal 7JawabanA.42B.46C.41D.51

1. ### Break Down the Problem

We need to find the 11th term of the arithmetic sequence given: 6, 10, 14, 18, ....

2. ### Relevant Concepts

In an arithmetic sequence, each term can be calculated using the formula: $a_n = a_1 + (n - 1) \cdot d$ where:

• $a_n$ = the nth term of the sequence
• $a_1$ = the first term of the sequence
• $d$ = the common difference
• $n$ = the term number

3. ### Analysis and Detail

1. Identify $a_1$ and $d$:

   • First term $a_1 = 6$
   • Common difference $d = 10 - 6 = 4$

2. Use the formula to find the 11th term ($n = 11$): $a_{11} = 6 + (11 - 1) \cdot 4$

3. Calculate: $a_{11} = 6 + 10 \cdot 4 = 6 + 40 = 46$

4. ### Verify and Summarize

The calculations confirm that the 11th term in the sequence is indeed 46.

Final Answer

The suku ke-11 barisan tersebut adalah 46 (Jawaban B).
