Question

What is the rule for the following sequence? 4.1, 4.6, 5.1, 5.6, 6.1,... A. Add 5 to the previous term. В. Add 0.5 to the previous term. C. Multiply the previous term by 5.D. Divide the previous term by 5.

Answer 1

Starting from 4.1, notice that if we add 0.5

$4.1+0.5=4.6$

We get the second term. If we do the same,

$4.6+0.5=5.1$

We get the third. Repeating once more,

$5.1+0.5=5.6$

We get the fourth, and so on.

Therefore the rule for the following sequence is

B. Add 0.5 to the previous term.
