Find the first 4 terms of the given rule an=3n-2.
substitute 1 , 2 , 3 , and 4 for n to find the 1st four terms
Very poor in mathematics
To find the first 4 terms of the given rule with the formula "an = 3n - 2", you simply need to substitute the values of n starting from 1 up to 4.
Let's calculate each term one by one:
For n = 1:
a1 = 3(1) - 2
a1 = 3 - 2
a1 = 1
Therefore, the first term (a1) is 1.
For n = 2:
a2 = 3(2) - 2
a2 = 6 - 2
a2 = 4
Therefore, the second term (a2) is 4.
For n = 3:
a3 = 3(3) - 2
a3 = 9 - 2
a3 = 7
Therefore, the third term (a3) is 7.
For n = 4:
a4 = 3(4) - 2
a4 = 12 - 2
a4 = 10
Therefore, the fourth term (a4) is 10.
Hence, the first four terms of the given rule an = 3n - 2 are: 1, 4, 7, 10.
