Define a sequence by a1=3 and an=3an−1. Find the first four terms of the sequence. Give a simplified integer answer.
aalyn [17]

Answer:

The first four terms are 3,9,27,81

Step-by-step explanation:

<u>Step :-1</u>

Given first term of sequence is a_{1} = 3

Given 'n' t h term is a_{n} = 3 a_{n-1}  .............(1)

here we put  n = 2 in equation (1)

a_{2} = 3a_{2-1}

a_{2} = 3 a_{1}    ..............2

put a_{1} = 3      in equation (2)

a_{2} = 3(3)  

a_{2} = 9

put n=3 in equation (1)

a_{3} = 3 a_{3-1}

a_{3} = 3a_{2}

a_{3} = 3 (9) = 27

put n= 4 in equation (1)

a_{4} = 3 a_{4-1}

a_{4} = 3 a_{3}

a_{4} = 3(27) = 81

The first four terms of the sequence is

3 , 9, 27 , 81 ....this is geometric sequence

a =3 and ratio term is r =3
