Answer:
Hope This Helps
Step-by-step explanation:
The common difference (d) = 2
The first element (a) = 3.
So, the n-th term is
I = a + (n-1).d
= 3 + (n-1)×2
= 1 + 2n.
So the required sum is
= (n/2)(a + I)
= (n/2)( 3 + 1 + 2n)
= (n/2)(4 + 2n)
= n (n+2)

Answer:
only the first two are correct (top to bottom)
Step-by-step explanation:
For the first one, we know this because the the opposite of -3.5 is 3.5, and the rightside of zero is positive.
For the second one, we know the expression, -(-3.5) is equal to 3.5 because whenever there is a minus before a parentheses and there's a minus sign inside of the parentheses it automatically becomes positive.
For the third one, we know it's incorrect because the opposite of a positive is a negative.
Lastly, for the last one, (the most bottom one) we know that the opposite of zero is negative zero.
Hope this helps!!!
Answer:
50th term is 164
Step-by-step explanation:
a(n) = 17 + 3(n - 1)
a(50) = 17 + 3(50-1)
a(50) = 17 + 3(49)
a(50) = 17 + 147
a(50) = 164
