What is the 10th term of a geometric sequence if a1 = 45 and the common ratio is 2?​

Sagot :

Given:

[tex]a_{1} = 45[/tex]

[tex]r = 2[/tex]

[tex]n = 10[/tex]

Required:

[tex]a_{10}[/tex]

Solution:

[tex]a_{n} = a_{1}r^{n - 1}[/tex]

[tex]a_{10} = 45(2^{10 - 1})[/tex]

[tex]\blue{a_{10} = 23040}[/tex]
