PROBLEM
Find the next four terms of the sequence an given the values: 16, 25, 36, 49, 64.
STEP 1
Assumptions1. The sequence is {an} with known values a0,a1,a,a3,a4 which are16,25,36,49,64 respectively.
. The sequence follows a certain pattern which we need to determine.
STEP 2
We observe the given sequence to identify a pattern.a0=16,a1=25,a2=36,a=49,a4=64
STEP 3
We notice that each number in the sequence is a perfect square.a0=2,a1=52,a2=62,a3=72,a=82
STEP 4
We can see that the base of the square for each term in the sequence is increasing by1 for each subsequent term.an=(n+4)2
STEP 5
We can now use this pattern to calculate the next four terms in the sequence.a5=(5+4)2,a=(+4)2,a7=(7+4)2,a8=(8+4)2
SOLUTION
Calculate the values of a5,a6,a,a8.
a5=92=81,a6=102=100,a=112=121,a8=122=144The next four values of the sequence {an} are81,100,121,144.
