Step-by-step explanation:

• First 10 multiples of 6 = 6,12,18,24,30,36,42,48,54,60
• Sum of first ten multiples of 6 = 6+12+18+24+30+36+42+48+54+60 = 330

Answer 2

To Find:

The sum of the first 10 multiples of 6.

Formula:

Sn = n/2 ( a + an )

Explanation:

First multiple (a) of 6 is 6, the 10th multiple (an) of 6 is 60 and no. of terms (n) is 10

Sn = 10/2 ( 6 + 60 )

Sn = 5 ( 66 )

Sn = 330
