Answer:

3, 8, 14, 30, 58

Step-by-step explanation:

As with all formulas, put the numbers in place of the corresponding variables, and do the arithmetic.

$a_1=3\qquad\text{given}\\\\a_2=8\qquad\text{given}\\\\a_3=2a_1+a_2=2(3)+8=14\\\\a_4=2a_2+a_3=2(8)+14=30\\\\a_5=2a_3+a_4=2(14)+30=58$

The first 5 terms of the sequence are 3, 8, 14, 30, 58.

Niko has an orange tree and a lemon tree in his backyard the orange tree is 7 feet tall 9 inches tall the lemon tree is 1 yard 2

Dennis_Churaev [7]

We can solve this by converting both measurements to inches.

Orange tree:
1 foot=12 inches
7 feet=84 inches
84 inches + 9 inches = 93 inches total

Lemon tree:
1 yard=3 feet=36 inches
2 feet=24 inches
36 inches + 24 inches + 5 inches=65 inches total

Therefore, the orange tree is taller than the lemon tree.
