Question

In a sequence starting at 10 with the term-to-term rule "subtract 3 then multiply by 2," what is the fourth term?

a) 2
b) 4
c) 6
d) 8

Answer 1

The fourth term of the sequence is 38

A sequence is an ordered list of elements following a specific pattern or rule.

In mathematics, sequences can be finite or infinite, and their terms may be numbers, functions, or other objects, each determined by a consistent rule.

The first term of the sequence is 10

The second term with the rule will be ;

(10-3)× 2 = 14

The third term will be

14-3) × 2 = 22

the fourth term is

(22-3) × 2 = 38

Therefore, the fourth term is 38
