Question

Find the four terms of the sequence given by the following expression

Answer 1

47, 40, 33, 26 are the first four terms of the sequence.

Explanation:

Expression representing the sequence is,

`a_n=46-7(n-1)`

where n = number of term in the sequence

For n = 1,

`a_1=47-7(1-1)`

= 47

For n = 2,

`a_2=47-7(2-1)`

= 47 - 7

= 40

For n = 3,

`a_3` = 47 - 7(3 -1)

= 47 - 14

= 33

For n = 4,

`a_4=47-7(4-1)`

= 47 - 21

= 26

Therefore, first four terms of the sequence are 47, 40, 33 and 26.
