Remark
You want the 60th term of the arithmetic (?) sequence given.
Formula
L = a + (n - 1)*d
Givens
L = ?
a = 8
d = 8
n = 60
Solution
L = 8 + (60 - 1)*8
L = 8 + 60*8 - 8
L = 480
Answer
The 60th term is 480
Answer:
Step by step explanation :
As we know
[tex]\:\bf\boxed{an\:=\:a\:+\:(n\:-\:1)\:d}[/tex]
where,
an = the nth term in the sequence
n = the term
d = common difference
a = first term of the AP.
Here,
an = a60
n = 60
d = 16 - 8 = 8
a = 8
Now,
[tex]\:\mathsf{a60\:=\:8\:+\:(60\:-\:1)(8)}[/tex]
=> [tex]\:\mathsf{a60\:=\:8\:+\:(59)(8)}[/tex]
=> [tex]\:\mathsf{a60\:=\:8\:+\:472}[/tex]
=> [tex]\:\bf{a60\:=\:480}[/tex]
Therefore the 60th term of the AP is 480.
