Question

Find the 10th term 3,15,75,375

Answer 1

Answer:

5859375

Step-by-step explanation:

These are the terms of a geometric sequence with n th term

$a_{n}$ = $a_{1}$ $r^{n-1}$

where r is the common ratio and $a_{1}$ the first term

here r = $\frac{375}{75}$ = $\frac{75}{15}$ = $\frac{15}{3}$ = 5 and $a_{1}$ = 3, hence

$a_{10}$ = 3 × $(5)^{9}$ = 5859375
