Question

find the sum of first 10 multiple of 6

Answer 1

Answer:330

Step-by-step explanation: 6,12,18.......

a=6

d=6

n=10

s=10/2[2*6+(10-1)(6)]

s=5[12+54]

s=5[66]

s=330

Answer 2

Answer:

330

Step-by-step explanation:

The first 10 multiples of 6 are as follows :

6 × 1 = 6

6 × 2 = 12

6 × 3 = 18

6 × 4 = 24

6 × 5 = 30

6 × 6 = 36

6 × 7 = 42

6 × 8 = 48

6 × 9 = 54

6 × 10 = 60

These are the first 10 multiples of 6.

Summing the numbers we have :

6 + 12 + 18 + 24 + 30 + 36 + 42 + 48 + 54 + 60 = 330
