Answer 1

Answer:

sum of first 10 natural numbers divisible by 4 is 220

hope it helps

Step-by-step explanation:

the first 10 natural numbers divisible by 4 are

4, 8, 12, 16, 20... so on

a = 4

d = 4

n = 10

Sn = n/2 ( 2a + (n-1) d)

S₁₀ = 10/2 ( 8 + (10-1)4)

     = 5 (8 + 36)

     = 5 * 44

     = 220

Answer 2

the first ten natural number divisible by 4 are:

4,8,12,16,20,24,28,32,36,40

so their sum =

4+8+12+16+20+24+28+32+36+40

= 220
