To find the difference between the 13th and 1st term, we need to substitute the values of n in the given nth term expression.
For the 1st term, n = 1:
log2(1 + 3) = log2(4) = 2 (since 2^2 = 4)
For the 13th term, n = 13:
log2(13 + 3) = log2(16) = 4 (since 2^4 = 16)
The difference between the 13th and 1st term is 4 - 2 = 2.
The nth term of a sequence is log2 (n+3). What is the difference between the 13th and the 1st term.
