Question

List the elements C={7n|n belongs to N, n<5}

Answer 1

Answer:

$C = \{0,7,14,21,28\}$

Step-by-step explanation:

Given

$C \{7n: n < 5\}$

Required

List the elements

Assume that n is not negative, the values of n are:

$n = \{0,1,2,3,4\}$

So, the values of C is:

$C = 7 * n$

$C = 7 * \{0,1,2,3,4\}$

Multiply each set element by 7

$C = \{7 *0,7 *1,7 *2,7 *3,7 *4\}$

$C = \{0,7,14,21,28\}$
