Question

What is the eighth term in the sequence 4, 8, 12, 16, 20…?

Answer 1

32

Explanation:

The pattern is multiples of 4

The 8 term will be the 8 multiple of 4

4 * 8 = 32

Answer 2

32

Explanation:

We are adding 4 each time

an = a1+d(n-1)

an = 4+4(n-1)

we want the 8th term

a8 = 4+4(8-1)

a8 = 4+4(7)

a8 = 4+28

a8 = 32
