Find The First 5 Terms Of The Sequence Given The Nth Term?, 1.An=N+7, 2.An=2n -3, 3.An=12 -4n, 4.An=2n, 5.An=(-3)N

Find the first 5 terms of the sequence given the nth term?

1.an=n+7
2.an=2n -3
3.an=12 -4n
4.an=2n
5.an=(-3)n

Answer:

Step-by-step explanation:

an=n+7

Substitute the Values to n

a1=8

a2=9

a3=10

a4=11

a5=12

an=2n -3

Substitute the Values to n

a1=2(1) -3

a1= -1

a2=2(2) -3

a2=1

a3=2(3) -3

a3=3

a4=2(4) -3

a4=5

a5=2(5) -3

a5=7

an=12 -4n

a1=12−(4)(1)

a1=8

a2=12−(4)(2)

a2=4

a3=12−(4)(3)

a3=0

a4=12−(4)(4)

a4=−4

a5=12−(4)(5)

=−8

4.an=2n

a1=(2)(1)

a1=2

a2=(2)(2)

a2=4

a3=(2)(3)

a3=6

a4=(2)(4)

a4=8

a5=(2)(5)

a5=10

5.an=(-3)n

a1=(−3)(1)

a1=−3

a2=(−3)(2)

a2=−6

a3=(−3)(3)

a3=−9

a4=(−3)(4)

a4=−12

a5=(−3)(5)

a5=−15
