the 20th term of a sequence with nth term 3+4(n-1) is what?
Well, at the 20th term, n is 20.
Does knowing that help?
To find the 20th term of the given sequence, we can use the formula for the nth term of a sequence. The nth term is given by the formula:
nth term = 3 + 4(n - 1)
In this formula, n represents the term number. To find the 20th term, substitute n = 20 into the formula:
20th term = 3 + 4(20 - 1)
Simplify the expression inside the brackets:
20th term = 3 + 4(19)
Multiply 4 by 19:
20th term = 3 + 76
Add 3 and 76:
20th term = 79
Therefore, the 20th term of the sequence is 79.
