Evaluate the summation of 3 n plus 2, from n equals 1 to 14. 39 49 340 343.
lord [1]

The summation of the considered expression in terms of n from n = 1 to 14 is given by: Option D: 343

<h3>How to find the sum of consecutive integers?</h3>

1 + 2 + 3 + ... + n = \dfrac{n(n+1)}{2}

<h3>
What are the properties of summation?</h3>

\sum_{i=r}^s  (a \times f(i) + b) = a \times [\: \sum_{i=r}^s f(i)] + (s-r)b

where a, b, r, and s are constants, f(i) is function of i, i ranging from r to s (integral assuming).

For the given case, the considered summation can be written symbolically as:

\sum_{n=1}^{14}  (3n + 2)

It is evaluated as;

\sum_{n=1}^{14}  (3n + 2) = 3 \times [ \: \sum_{n=1}^{14} n ] + \sum_{n=1}^{14} 2\\\\\sum_{n=1}^{14}  (3n + 2) = 3 \times \dfrac{(14)(14 + 1)}{2} + (2 + 2 + .. + 2(\text{14 times}))\\\\\sum_{n=1}^{14}  (3n + 2) = 3 \times 105 + 28 = 343\\

Thus, the summation of the considered expression in terms of n from n = 1 to 14 is given by: Option D: 343

Answer:

Well, 2 quarters are 2 coins. But, if you are asking the value of 2 quarters, then your answer will be, 50.
