The pattern is add 7 each time, so all you have to do is write it out and add them all up!

1,254

Sum of N term is 1,254

Given that;

Number of term = 19

Sequence = 3,10,17,24,31

Find:

Sum of 19 term

Computation:

Sum of N term = [n/2][2a + (n-1)d]

Sum of N term = [19/2][2(3) + (19-1)(7)]

Sum of N term = [19/2][6 + (18)(7)]

Sum of N term = [19/2][132]

Sum of N term = [19][66]

Sum of N term = 1,254
