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
B. 18.37
1990 - 1960 = 30 = t
Plug in the variable "t" to the equation and solve.
P (t) = 18.37
The hundred thousand place is the number that is 6 times to the right of the decimal:
In this case that number is 2
Answer:
|-8| < |7| is FALSE
Step-by-step explanation:
The absolute value of -8 is 8, which is greater than 7, not less than.
I’m 99% sure the answer is:
c: 2t - d = 260
t - d = 320
