Step-by-step Solution
To find the sum of the first 4 terms in the sequence \( x_{n}=\{7,11,15,19\} \), you simply add the terms together:
\( x_1 = 7 \)
\( x_2 = 11 \)
\( x_3 = 15 \)
\( x_4 = 19 \)
Sum = \( x_1 + x_2 + x_3 + x_4 \)
Sum = \( 7 + 11 + 15 + 19 \)
Sum = \( 52 \)
The sum of the first 4 terms in the sequence is 52.
Quick Answer
The sum of the first 4 terms is 52.
