Find the 35th term in the arithmetic sequence: -10, -14, -18, -22,...

Mathematics
1 answer:
LUCKY_DIMON [66]3 years ago
6 0

Step-by-step explanation:

-10, -14, -18, -22,...

a1 =  - 10 \\ a2 =  - 14 \\ d = a2 - a1 \\ d =  - 14 -  - 10 \\ d =  - 14 + 10 =  - 4 \\ an = a1 + (n - 1)d \\ a35 =  - 10 + (35 - 1) \times ( - 4) \\ a35 =  - 10 + 136 \\ a35 = 126

Y = mx + b, where m = slope = rise/run and b, the y intercept value

m = 1/1 = 1, then y = x + b.
We notice that y intercept is = - 1
And the equation is:

y = x - 1

Is Jeff correct or incorrect?
bulgar [2K]
Jeff is correct because:

2 sides of a triangle must always be longer than the other side, so:

12+8>19
19+8>12
12+19>8

Since all of them are true, Jeff is correct

d=\sqrt{36+49}\implies \boxed{d=\sqrt{85}}\\\\
