Icreased shells = 49 - 40 = 90

\text{Percentage increase = $\dfrac{49- 40}{40}*100$}

What is 1/2 plus 1/3
IgorC [24]
First you have to make them both common denominators
the common denominator is 6 so then half of 6 is 3 so it is 3/6 and then 1/3 converted to a denominator of 6 is 2/6 so the answer is 3/6+2/6= 5/6

Suppose that a sequence is defined as follows. This the 1st four terms of the sequence. ASAP BRANLIEST TY!!​
SashulF [63]

Answer:

- 3, 16, - 22, 54

Step-by-step explanation:

Using the recursive formula with a₁ = - 3, then

a₂ = - 2a₁ + 10 = - 2(- 3) + 10 = 6 + 10 = 16

a₃ = - 2a₂ + 10 = - 2(16) + 10 = - 32 + 10 = - 22

a₄ = - 2a₃ + 10 = - 2(- 22) + 10 = 44 + 10 = 54

Thus

the first 4 terms of the sequence are

- 3, 16, - 22, 54
