Question

Find the first 5 terms of the sequence: aa = 2n - 5. Enter your answers separated by commas; example: -1, 2, -3, 4, -5.

Answer 1

n is the natural number
so just put n=1,2,3,,4,5 in this equation

a = 2n-5
for n=1
a1=2-5 =-3
a2=2(2)-5=4-5=-1
a3=2(3)-5= 6-5=1
a4=2(4)-5= 8-5=3
a5=2(5)-5= 10-5=5
the first five terms are given below
-3,-1,1,3,5
this is the correct answer

@geerky42

Answer 16

aa=2n-5

Answer 17

Well, in that case, I guess sequence goes like this: \(2n-5,~2n-5,~2n-5,~2n-5,~2n-5\)

Answer 44

@HARSH123

Answer 45

So if you want the first 5 terms, you want A1, A2, A3, A4, and A5.
An = 2n-5
So A1 = 2(1) - 5 = -3
A2 = 2(2) - 5 = -1
A3 = 2(3) - 5 = 1
A4 = 2(4) - 5 = 3
A5 = 2(5) - 5 = 5
-3, -1, 1, 3, 5
