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

soldi70 [24.7K]

Answer:

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

Step-by-step 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.

The circumference of a circle is 60 pi cm. What is the radius of the circle?

Ivenika [448]

Answer:

Step-by-step explanation:

The formula for the circumference of a circle is 2 $\pi$ r. So if we know that C=60 $\pi$ then we can trace our steps back. We are given that pi remains constant so we are left with the 2r from the formula and a 60. 60/2 =30.
