Question

How many terms are there in the expression 2x -5y + 3 + x?

Answer 1

there are 4 terms are there in expression.

Answer 2

short trick to finding the no of term :

if sereis is(k1 + k2 + ...)^ n

then no of term = n+k-1

C

k-1

here's k= 4 and n= 1

no of term = 1+4_1

C

4-1

= 4!/(3!4-3! = 4×3!/3!×1 = 4

so, in the given sereis, total no of terms are = 4
