Find the first four terms of the arithmetic sequence
where a1 = 2 and d = 5 (use formula)

first four terms are 2, 7, 12, 17

Step-by-step explanation:

use this formula:   = + (n - 1)· d

where 'n' equals the position in the sequence the term is in and 'd' is the common difference

if = 2 and d = 5 are given, plug those into formula

= 2

= 2 + (2 - 1)·5 = 2+5 = 7

= 2 + (3 - 1)·5 = 2+2(5) = 12

= 2+(4 - 1)·5 = 2+3(5) = 17

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
