P → q

EXPLANATION

p → q is a symbol for a conditional statement, an if-then statement in which p is a hypothesis and q is a conclusion. The logical connector in a conditional statement is denoted by the symbol →.

The conditional is defined to be true unless a true hypothesis leads to a false conclusion.

Evaluate the summation of 2n+5 from n=1 to 12 29 36 216 432

rewona [7]

$\bf \sum\limits_{n=1}^{12}\ 2n+5\implies \sum\limits_{n=1}^{12}\ 2n+\sum\limits_{n=1}^{12}\ 5\implies 2\sum\limits_{n=1}^{12}\ n+\sum\limits_{n=1}^{12}\ 5
\\\\\\
2\cdot \cfrac{12(12+1)}{2}+(12\cdot 5)\implies 156+60\implies 216$
