Sagot :
Answer:
The [tex]n^{th}[/tex] sequence aₙ = -15 +5n
The fifth term of the sequence
a₅ = 10
Step-by-step explanation:
Step(i):-
Given sequence
-10,-5,0,5,10,15,20,.....
The first term = -10
The difference of two terms in the given sequence is equal
d = -5-(-10) = -5 + 10 = 5
d = 0 -(-5) = 5
The given sequence is in arithmetic progression
Step(ii):-
The [tex]n^{th}[/tex] sequence
[tex]a_{n} = a+(n-1) d[/tex]
aₙ = -10 +(n-1) 5
aₙ = -10 + 5n -5
aₙ = -15 +5n
Step(iii):-
The [tex]n^{th}[/tex] sequence aₙ = -15 +5n
put n = 5
a₅ = -15 + 5(5) = -15 +25 = 10
Final answer:-
The [tex]n^{th}[/tex] sequence aₙ = -15 +5n
The fifth term of the sequence
a₅ = 10
Answer:
The sequence starts with -10, and the index starts at 1. So, the index of -10 is 1.
n = 5 refers to the fifth term of the sequence, which is 10.
