Step-by-step explanation:
The formula for an arithmetic sequence is An=A1+(n-1)d.
Using this knowledge, you can set up the equation easily to be An=1+(12-1)-5
You then simplify this to 1-55 using PEMDAS, giving you the answer for the twelfth term being -54, you then do this for every term if you want (or you could just subtract 5 by the terms after 14 till you get to -54. After all that, you add the twelve terms up to get -319 as your final answer
Answer:

3/14 * square root 98 =
= square root of 98 * 3/14^2 =
= square root of 98 * 9/196 =
= square root of 9/2
3/2 * square root of 2 =
= square root of 2 * 9/4 =
= square root of 9/2
square root of 9/2 = square root of 9/2
