What is the value of the 24th term in the following arithmetic sequence?
-9, -2, 5, 12, ...
A. -170
B. 152
C. -200
D. 170
Answer:
Option B
Step-by-step explanation:
[tex]a_{n}=a_{1} +d(n-1)\\a_{n}=-9 +7(n-1)\\a_{24}=-9 +7(24-1)\\a_{24}=-9 +7(23)\\a_{24}=-9 + (161)\\\\a_{24}=152\\[/tex]
a=-9
d=-2-(-9)
= 7
d= 5-(-2)
= 5+2
=7
a24 = a+23d
= -9 + 23×7
= -9 + 161
a24 = 152
so, answer is b.152
