Answer:

1

Step-by-step explanation:

21 = 3*7

65 = 5*13

CGF: to find the greatest common factor, multiply those factors both numbers have in common

GCF :1  since there are no factors in common

Answer:  1 ✔


Step-by-step explanation:

The factors of 21 are: 1, 3, 7, 21

The factors of 65 are: 1, 5, 13, 65

Then the greatest common factor is 1.

They both contain a one in their factors so the GCF for both is 1.

Find the sum of natural number from 1 to 30
Ierofanga [76]

Answer:

1. sum of term = 465

2. nth term of the AP = 30n - 10

Step-by-step explanation:

1. The sum of all natural number from 1 to 30 can be computed as follows. The first term a = 1 and the common difference d = 1 . Therefore

sum of term = n/2(a + l)

where

a = 1

l = last term = 30

n = number of term

sum of term = 30/2(1 + 30)

sum of term = 15(31)

sum of term = 465

2.The nth term of the sequence can be gotten below. The sequence is 20, 50, 80 ......

The first term which is a is equals to 20. The common difference is 50 - 20 or 80 - 50 = 30. Therefore;

a = 20

d = 30

nth term of an AP = a + (n - 1)d

nth term of an AP = 20 + (n - 1)30

nth term of an AP = 20 + 30n - 30

nth term of the AP = 30n - 10

The nth term  formula can be used to find the next term progressively.  where n = number of term

The sequence will be 20, 50, 80, 110, 140, 170, 200..............
