An arithmetic series a consists of consecutive integers that are multiples of 4 what is the sum of the first 9 terms of this seq
frez [133]
<h3>Answer: 144</h3><h3>Step-by-step explanation:</h3><h3 />

Since, the first 9 multiple of 4 starts from 0 are,

0, 4, 8, 12, 16, 20, ................

Which is an AP,

Having the first term, a_1 = 0

And, the successive difference, d = 4,

Since, the sum of the n term of an AP,

S_n = \frac{n}{2}[2a + (n-1)d]

Hence the sum of 9 term of the above AP,

S_9 = \frac{9}{2}[2\times 0 + (9-1)\times 4]

S_9 = \frac{9}{2}(0 + 8\times 4)

S_9 = \frac{9}{2}(32)

S_9 = \frac{288}{2}=144
