Explanation

This is an arithmetic sequence with first term a = 2, last term l = 100, and common difference d = 2.

Step 1: Find the number of terms (n)

The nth term of an arithmetic sequence is given by: l = a + (n - 1)d

100 = 2 + (n - 1)2

100 = 2 + 2n - 2

100 = 2n

n = 50

Step 2: Calculate the sum of the sequence

Sum = n/2 * (a + l)

= 50/2 * (2 + 100)

= 25 * 102

= 2550

Explanation

This is an arithmetic series:

2, 6, 10, 14, ...

First term (a) = 2

Common difference (d) = 6 - 2 = 4

Number of terms (n) = 12

Sum of n terms of an arithmetic series:

S = n/2 × [2a + (n - 1)d]

S = 12/2 × [2×2 + (12 - 1)×4]

S = 6 × [4 + 44] = 6 × 48 = 288

Explanation

Step 1: Solve the inequality

x + 3 < 9

x < 9 - 3

x < 6

Explanation

Step 1: Isolate x

6x - 4 = 3x + 8

6x - 3x = 8 + 4

3x = 12

Step 2: Solve for x

x = 12 / 3

x = 4

Explanation

Step 1: Solve for x

3x + 5x = -8

8x = -8

x = -8 / 8

x = -1

Step 2: Calculate 2x + 1

2x + 1 = 2(-1) + 1

= -2 + 1

= -1
