Q. The first three terms of a sequence are given. Write your answer as a decimal or whole number. Round to the nearest thousandth (if necessary).6,2,32,…Find the 6th term.Answer:
Identify Pattern: Identify the pattern in the sequence.The sequence given is 6,2,32,… To find the pattern, we look at how each term is related to the previous one. We divide each term by 3 to get the next term.6÷3=22÷3=32This is a geometric sequence with a common ratio of 31.
Use Formula: Use the formula for the nth term of a geometric sequence.The nth term of a geometric sequence is given by the formula:an=a1⋅r(n−1)where an is the nth term, a1 is the first term, r is the common ratio, and n is the term number.
Plug in Values: Plug in the values to find the 6th term.a1=6 (the first term)r=31 (the common ratio)n=6 (we want to find the 6th term)a6=6×(31)6−1a6=6×(31)5
Calculate 6th Term: Calculate the 6th term.a6=6×(1/3)5a6=6×(1/243)a6=6/243a6=2/81
Convert to Decimal: Convert the fraction to a decimal and round to the nearest thousandth if necessary.812 as a decimal is approximately 0.0247Rounded to the nearest thousandth, it is 0.025.
