The answer is 1. I got this by dividing 118 by 9 and the 9 times 13 which equals 117. 117+1= 118
an explicit formula for the arithmetic sequence -5,13,31,49 is .
<u>Step-by-step explanation:</u>
Here we have an arithmetic sequence -5,13,31,49 . We need to find an explicit formula for the arithmetic sequence .Let's find out:
Let be terms of an A.P , common difference is :
⇒
⇒
⇒
⇒
We know that general term of an Arithmetic Progression ( A.P) is :
⇒
So , Here we will have
⇒
⇒
⇒
Therefore , an explicit formula for the arithmetic sequence -5,13,31,49 is .
If the check mark is a square root the next step is -2 x 2.2
Answer:5
That is exactly correct! Just two things: First, tan,sin,cos, etc hold no meaning on their own, they need an argument. So just be sure to write tanx, cosx etc rather than just tan or cos.
Finally, you could save time on your proof by noticing on the fourth step that
1cosxsinx=1cosx1sinx=secxcscx
