The first term of an arithmetic sequence is 14. The 25th term is 206. What is the common difference of the arithmetic sequence?

larisa [96]

an = a1+ d(n-1)

a1 =14

an=206 when n=25

206 = 14 + d (25-1)

206 = 14 + d * 24

subtract 14 from each side

192 = 24d

divide by 24 on each side

d=8

The common difference is 8

Please help me Solve -2a -5>3

worty [1.4K]

Answer:

a < -4

Step-by-step explanation:

Step 1: Write out inequality

-2a - 5 > 3

Step 2: Add 5 to both sides

-2a > 8

Step 3: Divide both sides by -2

a < -4

Here, we can see that any value of <em>a </em>less than -4 works. So <em>a</em> could be -124 or -5, or even -1271293587923857 and it would work.
