Question

Find the 6th term of the sequence with t1 = -4 and tn = 5tn-1.

Answer 1

is the equation

\[t_{n} = 5t_{n -1}\]

Answer 2

yeah

Answer 3

ok... so its basically

5 x the previous term

so

\[t_{2} = 5\times t_{2 -1}...... t_{2} = 5 \times t_{1} \]

you can repeat the process... until you get to the 6th term

or you can use the formula

\[T_{n} = ar^{n -1} \]

to find a term in a geometric series.. a = 1st term r = common ratio... n = number of terms

Answer 4

ok thanks
