If the nth term of a number sequence is n^2+4<br>find the first 3 terms and the 10th term.​
Colt1911 [192]

Answer:

a) The sequence of first three terms

5 , 8 , 13 ..

b) The 10^{th} of the sequence

a₁₀ = 104

<u><em></em></u>

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given n^{th} term of the sequence

  aₙ = n² + 4

put n=1

First term  a₁ = 1² +4 = 1+5

put n =2

Second term a₂ = 2²+4 = 4+4 =8

Put n=3

Third term a₃ = 3² +4 = 9+4 =13

The sequence of first terms

5 , 8 , 13 ..

<u><em>Step(ii):-</em></u>

Given n^{th} term of the sequence

  aₙ = n² + 4

put n =10

a₁₀ = 10²+4 = 100+4 = 104

a₁₀ = 104

The 10^{th} of the sequence

a₁₀ = 104

<u><em></em></u>
