Question

The sum of successive odd numbers 1, 3, 5, 7, 9, 11, 13 and 15 is ______. /​

Answer 1

Answer:

64

Step-by-step explanation:

1+3+5+7+9+11+13+15=64

Answer 2

Answer:

a¹ = 1

a² = 3

d = 3-1=2

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

n = 8

S⁸ = 8/2 (2(1) + (8-1)2)

S⁸ = 4(2+(7)2)

s⁸ = 4(2+14)

s⁸ = 4(16)

S⁸= 64

Step-by-step explanation:

Therefore : 64 is the sum of the successive odd number
