Step 1
In algebra, an equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expression that have the same value.
The most basic and common algebraic equations in math consist of one or more variables. For instance, x9=7 is an equation, in which x9 and 7 are two expressions separated by an ‘equal’ sign.
Step 2
Now substitute values of n from 1 to 8 in the equation and add them to obtain the summation of the series.
n=18(3n4)=(3×14)+(3×24)+(3×34)+(3×44)+(3×54)+(3×64)+(3×74)+(3×84)
=1+2+5+8+11+14+17+20
=76
