Find the 30th term of the following sequence. 1, 7, 13, 19,.. 174. 175. 180. 181.

1 answer:

8 0

The first term a = 1,

Common difference, d: 7 - 1 = 6.

a(n) = a + (n -1)d,

For 30th term. = 1 + (30 -1)*6

= 1 + 29*6 = 1 + 174 = 175

Answer:

Refexive I think

Step-by-step explanation:

5(3) = 3(5)

x(y) = y(x)

I found this

"Anything equals itself: this is the "reflexive" (reflecting onto itself) property. Also, it doesn't matter which order the equality is in; if x = y, then y = x: this is the "symmetric" (they match) property."
