What is the 50th term of the sequence that begins -4, 2, 8, 14....?
vagabundo [1.1K]

Answer:

a_{50}=290

Step-by-step explanation:

Notice that we are in the presence of an arithmetic sequence (there is a common difference of 6 between a term and the next). So thisis an arithmetic sequence with first term a_1=-4. and common difference "<em>d</em>" = 6.

Recall now the formula for the nth term (a_n) of an arithmetic sequence:

a_n=a_1+(n-1)\,d

Then, using our values in the formula, we get:

a_n=a_1+(n-1)\,d\\a_{50}=-4+(50-1)\,6\\a_{50}=-4+(49)\,6\\a_{50}=290

True or false: for any function, x=f^-1(y), then y=f(x)
kozerog [31]

YES

We can work out the inverse using Algebra. Put "y" for "f(x)" and solve for x:

<span><span>The function: f(x)=2x+3
</span><span>Put "y" for "f(x)": y=2x+3
</span><span>Subtract 3 from both sides:
 y-3=2x
</span><span>Divide both sides by 2:
 (y-3)/2=x
</span><span>Swap sides: x=(y-3)/2</span><span>  
   </span><span><span>Solution (put "f-1(y)" for "x") :</span> <span>f-1(y)</span>=(y-3)/2</span></span>
