First of all the consecutive terms are called Arithmetic Progression (AP).
So this is my 150th answer
Formula = n/2( 2a + (n-1)d )
here n is the number of terms till which we are summing the AP
here a stands for the first term of the given AP
here d stands for the common difference between the terms of an AP
Hope this helps

a-first term
n-number of terms
d-difference b/w two consecutive numbers
an or l-last term
the difference between two consecutive numbers will be 1
therefore we can find out sum by taking 1 as difference and first term as a
n-number of terms

not good enough
