List the first four terms of a geometric sequence with t1 = 4 and tn = -3tn-1.
How do I find r???
Hello, dzomberg!
List the first four terms of a geometric sequence with:-
How do I find ?
Just read what you are given . . . and crank out the list.
. . . The first term is 4.
. . . Each term is -3 times the preceding term.
Therefore:
. .
....And please learn to use LaTeX (as in our LaTeX help forum) or learn how to use parenthesis. tn = -3t(n-1) is a bit better anyway. t_n = -3t_(n - 1) would be best.
