Answer:
1, 17, 33, 49
Step-by-step explanation:
given the first term is 1 then the next 3 terms are
1 + d, 1 + 2d, 1 + 3d ( d is the common difference )
the sum of the first 4 terms is 100 , then
1 + 1 + d + 1 + 2d + 1 + 3d = 100 , that is
4 + 6d = 100 ( subtract 4 from both sides )
6d = 96 ( divide both sides by 6 )
d = 16
1 + d = 1 + 16 = 17
1 + 2d = 1 + 2(16) = 1 + 32 = 33
1 + 3d = 1 + 3(16) = 1 + 48 = 49
the first 4 terms are
1, 17, 33, 49

<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define</u>
5x + 3 - 2x = 12 + 7x - 2
<u>Step 2: Solve for </u><em><u>x</u></em>
- Combine like terms:                                                                                        3x + 3 = 7x + 10
- [SPE] Subtract 3x on both sides:                                                                    3 = 4x + 10
- [SPE] Subtract 10 on both sides:                                                                      -7 = 4x
- [DPE] Divide 4 on both sides:                                                                         -7/4 = x
- Rewrite:                                                                                                           x = -7/4
<u>Step 3: Check</u>
<em>Plug in x into the original equation to verify it's a solution.</em>
- Substitute in <em>x</em>:                     5(-7/4) + 3 - 2(-7/4) = 12 + 7(-7/4) - 2
- Multiply:                                -35/4 + 3 + 7/2 = 12 - 49/4 - 2
- Add:                                      -23/4 + 7/2 = 12 - 49/4 - 2
- Add:                                      -9/4 = 12 - 49/4 - 2
- Subtract:                               -9/4 = -1/4 - 2
- Subtract:                               -9/4 = -9/4
Here we see that -9/4 does indeed equal -9/4.
∴ x = -7/4 is the solution to the equation.
 
        
             
        
        
        
29.8 would be the number, but rounded would be 30
