Q. Find the 8th term of the geometric sequence shown below.−8x6,−8x7,−8x8,…Answer:
Find Common Ratio: To find the 8th term of the geometric sequence, we first need to determine the common ratio (r) of the sequence. The common ratio is found by dividing any term by the previous term.Calculation: r=−8x6−8x7=x7−6=x
Calculate 8th Term: Now that we have the common ratio, we can find the 8th term by using the formula for the nth term of a geometric sequence, which is an=a1⋅r(n−1), where a1 is the first term and n is the term number.Calculation: a8=(−8x6)⋅x(8−1)=(−8x6)⋅x7=−8x(6+7)=−8x13
