Answer 2

The Sum Of First Four Multiples Of 8 Is 80.

Step-by-step explanation:

Given:

First Term (a) = 8

Common Difference (d) = 8

Last term = 8 * 4 = 32

The AP goes like 8,16,24,32......

To Find:

The sum of first four multiples of 8.

Calculating:

Sn = n / 2 (a + l)

= 4 / 2 (8 + 32)

= (2) (40)

= 80

Therefore, the sum of first four multiples of 8 is 80.
