Question

Hi i need help what would be the 60th term in this sequence 4, 8, 12, 16, 20...NUMBER ELEVEN

Answer 1

Given the arithmetic sequence in the question, we can deduce that the common difference, d, is 4 and the first term, a1, is 4. The below formula will be used to solve for the 60th term of the sequence;

`a_n=a_1+(n-1)d`

Where a1 = first term = 4

d = common difference = 4

n = number of term = 60

Let's go ahead and substitute the given values into our equation;

`\begin{gathered} a_(60)=4+(60-1)4 \\ =4+(59)4 \\ =4+236 \\ =240 \end{gathered}`

Therefore, the 60th term of the sequence is 240.
