In a fish tank, 8/11 of the fish have a red stripe on them. if 16 of the fish have red stripes, how many total fish are in the tank?

We know that of the fish have a red stripe, and we know that this amount of fish that have red stripes are 16.

So then we can set up an equation to solve for the total amount of fish that are in the tank:

Then we solve for x by mutliplying by on both sides:

So now we know that there are 22 total fish in the tank.

i think the correct option is the second option.

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
