Answer:
The answer is 98,415
Step-by-step explanation:
This is because the pattern is to multiply by 3, when you keep on multiplying the term by 3 to get the next term until you get to the 10th term, the answer is 98,415.
Answer:
T10 = 98415
Step-by-step explanation:
The nth term of a GP series is Tn = ar^(n-1), where a = first term and r = common ratio .The general form of a GP is a, ar, ar^2, ar^3 and so on
T10 = ar^(10-1) = ar^9
here,
first term, a = 5
Common ratio, r determines how the next term varies in accordance with previous term
Getting the common ratio is by saying that
second term / first term = third term / second term
15 / 5 = 45 / 15
3 = 3
=> r = 3
Putting the values of a =5, r=3 in the formula T10 = ar^9
=> T10 = (5)(3)^9 (There was first of all problem of multiplication here)
= 5*19683
T10 = 98415
