If the pattern below follows the rule "add 6 to the previous number and then multiply the result by 3" what is the third number in the pattern, based on the initial number 1?
1, __, Δ, .....
1
(6+1)3 = 21
(6+21)3 = 81 etc....
To find the third number in the pattern, we first need to follow the given rule. The rule states that we need to add 6 to the previous number and then multiply the result by 3.
Starting with the initial number, which is 1, we can apply the rule step by step:
Step 1: Add 6 to the previous number (1 + 6 = 7)
Step 2: Multiply the result by 3 ((7) * 3 = 21)
Therefore, the third number in the pattern is 21.
