Question

From the formula 2s=n(a+1),find the value of s when n =30,a=35 and 1 =965
​

Answer 1

Answer:

2s=n(a+1)

2s=30(35+965)

2s=30(1000)

2s=30,000

s=30,000/2

s=15,000

The value of s is 15000.

Answer 2

2s = n (a+ 1)

n = 30

a = 35

1 = 965

2s = 30 ( 35 + 965 )

2s = 30 ( 1000 )

2s = 30000

s = 30000/2

s = 15000
