Answer:
= 
- 3
Step-by-step explanation:
A recursive formula allows a term in the sequence to be found from the previous term by adding the common difference to it.
Here d = 5 - 8 = - 3, thus
= - 3 with a₁ = 8 ← recursive formula
If my ans was helpful u can follow me
The elements you can see in the reaction are Calcium(Ca), Hydrogen(H), and Oxygen(O). So there are 3 elements in the chemical reaction.
Answer:
Number of children = x = 330
Number of adults = y = 358
Step-by-step explanation:
Let
Number of children = x
Number of adults = y
x + y = 688 (1)
1.75x + 2.00y = 1293.50 (2)
From (1)
x = 688 - y
Substitute x = 688 - y into (2)
1.75x + 2.00y = 1293.50
1.75(688 - y) + 2.00y = 1293.50
1,204 - 1.75y + 2.00y = 1293.50
- 1.75y + 2.00y = 1293.50 - 1,204
0.25y = 89.50
y = 358
Substitute y = 358 into (1)
x + y = 688
x + 358 = 688
x = 688 - 358
x = 330
Number of children = x = 330
Number of adults = y = 358
