Answer:
3, 5, 7, 9, 11, .........
Step-by-step explanation:
Given
= n(n + 2) , then
S₁ = 1(1 + 2) = 1(3) = 3 ⇒ a₁ = 3
S₂ = 2(2 + 2) = 2(4) = 8
S₃ = 3(3 + 2) = 3(5) = 15
Thus
a₂ = S₂ - S₁ = 8 - 3 = 5
a₃ = S₃ - S₂ = 15 - 8 = 7
The first 3 terms are 3, 5, 7
This is an AP with common difference d = 2, then
a₄ = a₃ + 2 = 7 + 2 = 9
a₅ = a₄ + 2 = 9 + 2 = 11
and so on
Step-by-step explanation:
Here's the answer I hope it will help you
Step-by-step explanation:
15 : 40
Both have table of 5 in common
5 : 8
Which of the lists is in order from smallest to largest? 1,330; 3,130; 3,310; 3,031 3,130; 3,031; 3,310; 1,330 1,330; 3,310; 3,0
lesantik [10]
Its the 4th because, 1,330 is the smallest then 3,031 is the second then, 3,130 is the third then fourth is 3,310
