Q. The first three terms of a sequence are given. Write your answer as a decimal or whole number. Round to the nearest thousandth (if necessary).11,15,19,…Find the 33rd term.Answer:
Identify Pattern: Identify the pattern in the sequence.The sequence starts at 11 and each term increases by 4 (15−11=4, 19−15=4).This is an arithmetic sequence with a common difference of 4.
Use Formula: Use the formula for the nth term of an arithmetic sequence.The nth term of an arithmetic sequence is given by an=a1+(n−1)d, where a1 is the first term, n is the term number, and d is the common difference.
Plug in Values: Plug in the values for the 33rd term.a1=11 (the first term), n=33 (since we want the 33rd term), and d=4 (the common difference).a33=11+(33−1)×4
Perform Calculation: Perform the calculation.a33=11+(32×4)a33=11+128a33=139
