What is the 15th term of the sequence A(n) = 50 - 3(n-1) ?
Alexus [3.1K]

Answer:

A(15)=8

Step-by-step explanation:

Given that,

A(n)=50 - 3(n-1)

We need to find the 15th term of the sequence. Put n = 15 in the above sequence so that,

A(15)=50 - 3(15-1)\\\\A(15)=50-3(14)\\\\A(15)=50-42\\\\A(15)=8

So, the 15th term of the sequence is 8.

I need some help with this math problem. I've had it explained to me two different ways. If x= -3 then what would be the answer
nadya68 [22]

Answer:

The square root of x will be evaluated first before the addition of 5. Hence (-3)^2 = 9 and 9 +5 = 14, as per your teacher's answer, which is correct. The answer would not be -4.
