# Find the first 5 terms of the sequence giventha nth term.

125/25=5

625/125=5

a=5

r=5

Sn = a r^N /n-1

5×( 5 )^n

Step-by-step explanation:

I hope it helps

an = 5n - 4

a₁ = 5(1) - 4

a₁ = 5 - 4

a₁ = 1

a₂ = 5(2) - 4

a₂ = 10 - 4

a₂ = 6

a₃ = 5(3) - 4

a₃ = 15 - 4

a₃ = 11

a₄ = 5(4) - 4

a₄ = 20 - 4

a₄ = 16

a₅ = 5(5) - 4

a₅ = 25 - 4

a₅ = 21

ANSWER: 1, 6, 11, 16, 21

An = (-2)ⁿ

a1=(−2)¹

a1=−2

a2=(−2)²

a2=4

a3=(−2)³

a3=−8

a4=(−2)⁴

a4=16

a5=(−2)⁵

a5=−32

#JuneChallenge

a1= 2

a2= 5

a3= 8

a4= 11

a5= 14

Step-by-step explanation:

3(1)-1

3-1

2

3(2)-1

6-1

5

3(3)-1

9-1

8

3(4)-1

12-1

11

3(5)-1

15-1

14

3,5,7,9,11

Step-by-step explanation:

a1=2(1)+1

=3

a2=2(2)+1

=5

a3=2(3)+1

=7

a4=2(4)+1

=9

a5=2(5)+1

=11

2. an = n² +7

a1 = 1² +7 = 8

a2 = 2² +7 = 11

a3 = 3² +7 = 16

a4 = 4² + 7 = 23

a5 = 5² + 7 = 32

8,11,16,23,32

3. an = 2n²

a1 = 2(1)²

= 2(1)

a1 = 2

a2 = 2(2)²

= 2(4)

a2 = 8

a3 = 2(3)²

= 2(9)

a3 = 18

a4 = 2(4)²

= 2(16)

= 32

a5 = 2(5)²

= 2(25)

a5 = 50

2,8,18,32,50

1st Term: 2

2nd Term: 5

3rd Term: 8

4th Term: 11

5th Term: 14

Step-by-step explanation:

1st Term:

an=3n-1

an=3(1)-1

an=3-1

an=2

2nd Term:

an=3n-1

an=3(2)-1

an=6-1

an=5

3rd Term:

an=3n-1

an=3(3)-1

an=9-1

an=8

4th Term:

an=3n-1

an=3(4)-1

an=12-1

an=11

5th Term:

an=3n-1

an=3(5)-1

an=15-1

an=14

10n yan ang sagot gayahin nyo lang yan

-2, -4, -6, -8 and -10

Step-by-step explanation:

to get the first 5 terms of this sequence substitute the first 5 natural numbers to n.

a_n = (-2)n

a_1 = (-2)1

a_1 = -2

a_2 = (-2)2

a_2 = -4

a_3 = (-2)3

a_3 = -6

a_4 = (-2)4

a_4 = -8

a_5 = (-2)5

a_5 = -10

Thus the first 5 terms are -2, -4, -6, -8 and -10.

#CarryOnLearning

Yung n sa An ay palitan mo lang ng 1 tapos sunod 2 tapos 3, hanggang 5 mo gawin para makuha mo yung first 5 terms nito
